Have an account? I've been a bartender for over a decade, but I still get frustrated by certain customer behaviors.  Yelling my name and waving money in my face when I'm clearly busy won't get my attention. It's usually best not to alter specialty drinks. I've been bartending for over a decade, and I can tell you it isn't easy. The job can be physically and mentally demanding while requiring long, late hours — plus, we have to be pretty charming while doing it. Sometimes customers can make our job better, but at the very least, we'd prefer if they don't make it worse. Next time you're out having a pint or a margarita with your pals, don't make these mistakes. Being obnoxious while trying to get a bartender's attentionThe most common customer offense, by far, is waving cash at the bartender, yelling their name, or otherwise trying to get their attention while they're doing something else.Most of the time, simply being at the bar without a fresh drink is enough to let the bartender know you want one.If you really think the bartender doesn't know you're waiting to order, some eye contact and a nod will suffice.Stepping up to a busy counter when you don't know what you want  Know your order before you steup up to the counter. Business Insider/Will Martin If the bar is busy and you have to wait to order a drink, take that time to figure out what you're going to get.Don't lose your spot in line with the bartender by saying "I don't know" or turning around to ask your friends what they want. They don't have time for that.Assuming a bartender's gender or sexualityAssuming the bartender's gender or sexuality is a great way to get ignored for the rest of the night.Also, if they want to flirt with you, you'll know. Otherwise, let's keep it professional. Trying to order a drink without an IDNobody cares about the story behind why you don't have your ID.A bartender usually isn't willing to risk their job or get into legal trouble just to help you out.Altering special cocktails on the menu The bartender usually knows best when it comes to mixed drinks. Maksym Fesenko/Shutterstock If you want to make your own cocktail recipes, do it at home.Nine times out of 10, the altered cocktail tastes like garbage and gets sent back. Just order a drink that sounds good to you as listed. Asking the bartender to play your musicIf there isn't a jukebox, the bar is not interested in hearing your playlists. Don't ask the bartender to change the music, play a song, or adjust the volume. They're not a DJ.Telling the bartender your first name for your tabWhen asked what the name on your tab is, give the bartender your last name.We know you think you're the only Brandon in here, but you're probably not. Relying on the bartender to remember your drink orderThey might remember it, or you might be getting them confused with the other bartender.Either way, it's better if you know your own order. Taking up more space than you need Being rowdy and taking up a lot of space in a bar can be rude. Nomad_Soul/Shutterstock Be mindful of other people's space at the bar.Don't lean over and take up multiple seats or leave your trash on the patio. And for heaven's sake, don't leave a trail of dirty glasses behind you while you're mingling — just bring your empty cup with you when you come up for your next drink.The less time the bartender has to spend cleaning up after you, the more time they can spend making everyone's drinks. Wasting time by asking what we haveDo you really want me to start listing everything we have? It's a bar. Read a menu or be more specific. Asking "What pilsners do you have?" or "What gins do you have?" is perfectly fine. That helps us to narrow it down a bit if we're going to have to help you figure out what you feel like drinking.Leaving only a verbal tipBartenders love compliments, but those don't pay the bills.Remember, we're working for money. If you really think they make the best margarita in town, show them with a big tip.This story was originally published on January 7, 2023, and most recently updated on May 29, 2025.

Artur Debat/Getty ImagesGenerative AI is an astonishing technology that's not only here to stay but promises to impact all sectors of work and business. It's already made unprecedented inroads into our daily lives.We all have a lot to learn about it. Spewing out a few prompts to ChatGPT may be easy, but before you can turn all these new capabilities into productive tools, you need to grow your skills. Fortunately, there is a wide range of classes that can help. Also: I let Google's Jules AI agent into my code repo and it did four hours of work in an instantMany companies and schools will try to sell you on their AI education programs. But as I'll show in the following compendium of great resources, you can learn a ton about AI and even get some certifications -- all for free.I have taken at least one class from each of the providers below, and they've all been pretty good. Obviously, some teachers are more compelling than others, but it's been a very helpful process. When working on AI projects for ZDNET, I've also sometimes gone back and taken other classes to shore up my knowledge and understanding.So, I recommend you take a quick spin through my short reviews, possibly dig deeper into the linked articles, and bookmark all of these, because they're valuable resources. Let's get started. Course selection: Huge, more than 1,500(!)

The company offers an enormous library of courses on a broad range of topics. There is a monthly fee, but many companies and schools have accounts for all their employees and students. Also: Want a top engineering job in 2025? Here are the skills you need, according to LinkedInLinkedIn Learning is probably the one online education site I've used more than any other -- starting back in the late 1990s. For years, I paid for a membership. Then, I got a membership as an alum of my grad school, which is how I use it now. With so many courses on so many topics, it's a great go-to learning resource.I took two classes on LinkedIn Learning. Here's my testimonial on one of them. I also took the two-hour Machine Learning with Python: Foundations course, which had a great instructor -- Prof. Frederick Nwanganga -- who was previously unknown to me. I have to hand it to LinkedIn. They choose people who know how to teach.I learned a lot in this course, especially about how to collect and prepare data for machine learning. I also was able to stretch my Python programming knowledge, specifically about how a machine learning model can be built in Python. In just two hours, I felt like I got a friendly and comprehensive brain dump.You can read more here: How LinkedIn's free AI course made me a better Python developer.Since there are so many AI courses, you're bound to find a helpful series. To get you started, I've picked three that might open some doors:ChatGPT Tips for the Help Desk: Learn to apply strategic planning, prompt engineering, and agent scripting, as well as other AI techniques, to AI operations.Machine Learning with Python: Foundations: Get step-by-step guidance on how to get started with machine learning via Python.Building Career Agility and Resilience in the Age of AI: Learn how to reimagine your career to adapt and find success in the age of AI. It's worth checking with your employer, agency, or school to see if you qualify for a free membership. Otherwise, you can pay by month or year (the by-year option is about half price).A company representative told ZDNET, "LinkedIn Learning has awarded nearly 500K professional certificates over the past 2.5 years.

I conducted one of the first-ever academic studies of AI ethics as a thesis project way back in the day. I created and launched an expert system development environment before the first link was connected on the World Wide Web. I did some of the first research of AI on RISC-based computing architectures (the chips in your phone) when RISC processors were the size of refrigerators. I also wrote and deployed the AI Editor, a generative AI tool that built news and content dynamically. That may not seem like much today, but I did it way back in 2010, when I had to create a generative AI engine from scratch. At that point, to work, it had to be distributed across five individual servers, each running one agent of a team of clustered AI agents.Also: Six skills you need to become an AI prompt engineerI also have a master's degree in education, focusing on learning and technology. My specialty is adult online learning, so this kind of stuff is right up my alley. When it comes to the courses and programs I'm spotlighting here, there's no way I could take all of them. But I have taken at least one course from each vendor, in order to test them out and report back to you. And, given my long background in the world of AI, this is a topic that has fascinated and enthralled me for most of my academic and professional career.With all that, I will say that the absolute high point was when I could get an AI to talk like a pirate. Show more Some companies are promoting micro-degrees. They seem expensive, but fast, but are they any good? Let's be clear: A micro-degree is not a degree. It's a set of courses with a marketing name attached. Degrees are granted by accredited academic institutions, accredited by regional accrediting bodies. I'm not saying you won't learn anything in those programs. But they're not degrees and they may cost more than just-as-good courses that don't have a fancy marketing name attached. Show more So, do certificates have any value? Yes, but how much value they have depends on your prospective employer's perspective. A certificate says you completed a course of study successfully. That might be something of value to you, as well. Also: Want a job in AI? Check out these new AWS AI certificationsYou can set a goal to learn a topic, and if you get a credential, you can be fairly confident you have achieved some learning. Accredited degrees, by contrast, are an assurance that you not only learned the material but did so according to some level of standard and rigor common to other accredited institutions.My advice: If you can get a certificate, and the price for getting it doesn't overly stretch your budget, go ahead and get it. It still is a resume point. But don't fork over bucks on the scale of a college tuition for some promise that you'll get qualified for a job faster and easier than, you know, going to college.

It's been 12 months since Sarah Khan and her husband became digital nomads. Bali was her favorite place to work. Sarah Khan 2025-05-16T00:14:01Z Save Saved Read in app This story is available exclusively to Business Insider subscribers. Become an Insider and start reading now. Have an account? Last year, Sarah Khan, 33, and her husband moved out and became digital nomads. So far, they've worked from Bali, Rome, Tuscany, Bangkok, Phuket, and Alicante. Bali has been her favorite place to work. The Mediterranean sparkles to my left as I type from a foldable desk on the terrace of a cozy home in a quiet coastal town in Spain. Rolling green hills stretch to my right, framing the space that will be home for the next three months, until we pack up and move again.It's been 12 months since my husband and I embarked on a nomadic life. We sold everything, ended our four-year apartment lease in Singapore, and boarded a one-way flight to Bali. Since then, we've worked from Bali, Rome, Tuscany, Bangkok, Phuket, and now the coast of Alicante in Spain.Friends and fellow travelers often ask, "Where's your favorite place to work?" I'm sometimes hesitant to answer because it's so subjective. Choosing a base as a nomad involves a different set of criteria than picking a vacation spot. For me, factors like community, longer-stay visas, reliable WiFi, easy access to nature, and a vibrant wellness scene are at the top of the checklist. Still, if I had to choose, the place that stands out— and one I'd happily return to — is Bali. Rent for the villa in Bali was $1,800 a month, which included a pool, fast WiFi, and weekly cleaning. Sarah Khan I felt at homeBali was my first port of call as a digital nomad, and I spent a happy four months working and living there.Despite internet discourse about how "overrun" parts of the island have become, it remains my favourite place to work remotely to this day. Perhaps I'm biased — with my Indonesian roots and years of vacationing there, I feel instantly at home.My husband and I chose Berawa as our base, a laidback neighbourhood just outside the buzz of Canggu. Located on Bali's southern coast, Canggu has transformed from a sleepy surf village into the island's hippest enclave, packed with trendy cafés and black sand beaches that draw yogis and surfers in equal measure.This was my first time staying in Berawa, and it turned out to be the ideal spot for an extended stay. You get proximity to the action of Canggu without actually living in the thick of it. My two-bedroom villa, tucked down a quiet lane off a main road, placed me less than 10 minutes from central Canggu.Bali's cost of living has crept up in recent years, but it still offered value for our longer stay. Our villa rent was $1,800 a month, which included a pool, fast WiFi, and weekly cleaning — less than half of what I'd paid for my apartment in Singapore.A remote worker's dream setupBali was an easy place to get started on my nomad life. The island is exceptionally well-equipped for long stays: the WiFi is generally reliable, there are plenty of supermarkets and pharmacies available for daily necessities, and ride-hailing apps are affordable and convenient. After a year on the road, I've come to appreciate how rare this combination is.The island also boasts one of the best remote work ecosystems I've experienced, from coworking spaces like Outpost and BWork to laptop-friendly cafés. I rotated through a few favourites: the workspace upstairs at Woods, Zin Cafe, and Lighthouse, a coworking café with beautiful rice field views and its own on-site podcast and video studio. Lighthouse is a coworking café with beautiful rice field views. Sarah Khan It's also easy to stay active and healthy in Bali. Gyms, yoga studios, and affordable massages are aplenty, especially around Berawa. And food options are great: from warungs serving fragrant local dishes to health-forward cafés and world-class restaurants.When work felt overwhelming and I needed a break, I could hop on a scooter and be at the beach in minutes. There were also many options for weekend escapes: We managed trips to the pristine Nusa Lembongan and Ceningan islands, a day trip to serene Sidemen, and explored the east coast's slower-paced beach towns like Amed and Candidasa.These experiences revealed a quieter, more soulful side of Bali — one I'd missed on past short trips. Weekend escapes included a visit to an outdoor spa in Sidemen. Sarah Khan The downsidesOf course, no place is perfect. Traffic in Canggu can be chaotic, and the island's infrastructure is still catching up with its tourism growth. There's also a digital nomad community that, at times, can feel like a bubble and disconnected from authentic local life.But once you find your rhythm and favourite nooks, it's easy to tune out the noise and settle into Bali's slower, softer pace.I made it a point to skip the touristy spots, stay just outside the main areas, and design my life and routine around the kind of experience I wanted.A year into nomadic living, I've felt uprooted, disoriented, and occasionally exhausted. But in Bali, I found a version of myself I liked: Focused, centered, and rested. Recommended video
