Imagine how audacious you'd have to be to expect a free upgrade everywhere you go? Like if you were heading to the mechanic for a tire rotation and expected a full new set of tires. Or if you had coach tickets for your flight home for the holidays and Jeff Bezos just showed up to the tarmac insisting you take his private jet instead. Feels silly, huh?

Internet tutorials make DIY projects look like a walk in the park. Watching a sped-up video of a professional woodworker dismantling, staining, and rebuilding a piece of street furniture makes upcyclers green with envy, but whenever an amateur grabs the same set of tools, most people realize they're all thumbs.

This pool salesman has been on the job long enough to know that some customers can't be convinced to buy the products they need. Customers often like to think they know everything about a product just because they own it. In this case, the owner of a pool was pretty sure he knew everything he needed to know about his swimming pool. How hard could it be to maintain one little pool? All you have to do is fill it and empty it seasonally, and put in some chlorine or salt. Right? Surely there's noth…

This story is a peek into the a life of a DMV manager and her least friendly employee. If you've ever been to the DMV before, I'm so sorry. They're usually one giant room full of chairs and workers behind numbered desks. As a customer, you show up ready to renew a license or passport, and then it's time to wait. It's best to bring a book or a crossword puzzle and just expect that you may spend several hours there.

Is that you, Karen?

Usually once you've worked in the service industry, you learn how to be a good customer. Oftentimes, you'll learn how to respect your server, clean up after yourself, and generally be a half-decent human being while you're enjoying food at a restaurant. You'd think that it would be a natural reflex to be polite to the person handling your food supply, but for the disrespectful types, tormenting your server is a prize-winning sport.

You've probably heard about the “Ship of Theseus,” a paradoxical thought experiment that challenges you to question whether or not an object that has had all of its parts replaced is actually the same object anymore. Another variant of this is the "grandfather’s axe," which seeks to challenge whether or not an axe that has had its handle replaced and then later its head is really the same axe as it was before. Although not really quite the same philosophical question, I can't help but wonder… I…

Sometimes, the only way to deal with a Karen customer is to give them a taste of their own medicine. Here, we have a rare instance of a revenge tale that ends up having more of a wholesome ending. Who knew that getting payback could actually lead to positive change in your adversary's behavior? That's what this Redditor learned after they refused to let this regular customer get away with nonsense at the fast food restaurant where OP worked.

Everyone's stayed at a hotel or motel at least once in their life. The magical wonders of continental breakfasts, freshly made beds, and clean white towels get cemented in your memory, making your hotel experience (even the non-luxurious kind), memorable simply because it may be the one time in your life that you're pampered with room service. Your hotel experience is designed to go quite smoothly, that is, unless you're a poor listener and a tyrannical Karen...

Accusing a hotel front desk agent of fraud is probably not the best way to get them to help you. Remember: these are the people that can make your stay exponentially easier or exponentially more difficult. It's also worth noting that so much of this drama can be easily resolved if people remember to book their hotel stays directly on the hotel website rather than through a third-party site. The number of instances in which we have seen irate customers make this mistake through Internet stories…

Working in a call center is a pretty thankless gig. Constantly dealing with less-than-kind customers who are frustrated at your company's refusal to help them with their problem with your product—which to be fair, is a known issue that the company has deemed to be too expensive to resolve. So, now you're bearing the brunt of that frustration on a daily basis because your wage for 20 years still costs far less than paying R&D to fix the issue.

Even though she was only 17 years old, this woman was already an expert on koi and other tropical fish . It's fortuitous that she got a job to match, starting off at a retail tropical fish store. Whether you have a pet or not, spending time at pet stores is a fun and free activity to do. Many stores have tons of cats and dogs, some have gerbils or birds, and others have aisles and aisles of fish tanks. As far as retail jobs go, I imagine this is a pretty calm place to work most of the time.

Supermarkets are already a relatively overwhelming experience for most of us, akin to navigating a labyrinth that's been starkly lit by harsh-white fluorescent lighting while a string of the most infuriatingly mundane acoustic covers of songs that were popular ten years ago play omnipresently throughout.

"All of this is happening while she is allowing her dog to free roam the hotel..."

Have strength retail workers , you will need it when these customers show up. As a cashier, you'll ring up hundreds of customers each shift, and you'll probably forget all of them, except those who are exceptional. Maybe they're especially kind in a job where many customers are impolite. Or maybe they're really funny and manage to make you laugh. Or, if you're these people, you've remembered the customer because they've asked some of the most absurd questions ever. Several people who worked in…

Karens have the uncanny ability to identify, single out, and berate people who work customer service jobs, accosting them with wanton fury regardless of whether or not they even happen to be working at that time—or are even employed by that place at all.
