Dealing with difficult clients is part of many jobs, but some encounters push workers to the edge. Here are 12 unbelievable moments when entitled customers made employees question staying in their jobs — from absurd demands to pure disrespect.

One waitress saw a woman snatch back her tip, claiming they’d already “spent enough.” A retail worker had a customer rip a bag herself just to complain. A tech support agent refused to let an entitled caller manipulate him into bumping others’ appointments.

At a small-town fish and chip shop, customers threatened to go to “the competition” — not realizing the owners ran both shops. A manager predicted a chronic complainer would “see you next week,” and a waiter sarcastically warned a customer that their chicken was also “farm-raised.”

Other tales include habitual refund scammers, biscuit-obsessed customers, last-minute movers, a teen demanding free fries, and one Target employee who faked sign language to get a slow shopper to leave after closing.
