Thankfully, most of us can now admit that the customer isn’t always right . But that doesn’t necessarily make working with them any easier. You don’t need to have worked a single shift in retail or customer service to know that customers can be, at best, interesting —and at worst, a nightmare to keep happy. And every so often, one comes along who leaves you wondering what the heck just happened.

Those are the stories we’ve gathered here for you today: interactions that might’ve started off pretty normal and then, somewhere along the way, went entirely off the rails. They come from Not Always Right , a platform with a mission to “entertain, provide stress relief, and give a voice to everyday stories from workplaces, customer service, and beyond.” These stories range from hilarious to baffling to downright wholesome, and after reading them, you might just find yourself thinking: Yep, we hear you loud and clear.

The saying “the customer is always right” dates back to the early 20th century—and it’s probably been giving employees headaches for just as long. Its precise origins are a little murky, although it’s been associated with retail pioneers including Marshall Field, Harry Gordon Selfridge, and John Wanamaker. What does seem clear is that while some obnoxious customers might like to throw the adage around as something of a blanket claim to their irrefutable correctness on any and everything, the sentiment was intended to be more about putting customers’ needs and concerns first rather than catering to a customer’s every whim without question.

That distinction—between caring about a customer’s needs and catering to their every demand—is an important one that still matters today. Sure, customers can be frustrating , inconsistent, and sometimes flat-out wrong, but businesses have a very real reason to care about their satisfaction. And that’s not just a customer-service talking point, either.

Writing for Harvard Business Review, Rachel DuRose cites a 2021 McKinsey analysis that found U.S. leaders in customer experience achieved more than double the revenue growth of their less customer-focused peers. As the authors put it, “strategies focused on delighting customers allow companies to earn greater value from their current customer base—which results in concrete financial outcomes.”

But customer satisfaction is important in the bigger picture, too. The American Customer Satisfaction Index (ACSI) says that “changes in customer satisfaction affect the general willingness of households to buy,” and notes that because consumer spending accounts for 70% of U.S. GDP, changes in customer satisfaction “also correlate with changes in GDP growth.”

Lately, however, that satisfaction has been heading in the wrong direction: ACSI found that U.S. customer satisfaction fell from 76.7 in the first quarter of 2026 to 76.1 in the second, while customer complaints reached record levels.

That brings us back to the question of what it actually means to keep a customer satisfied. Because sometimes, a customer really is wrong. Maybe they’ve misunderstood a policy, expected something they were never promised, or want an exception that employees simply aren’t authorized to make. Telling them they’re wrong and leaving it at that probably isn’t going to make the interaction go any better.
