11 Disgustingly Rude Things Customers Have Done to Fast-Food Employees

6. “It’s difficult to pick the single rudest thing anyone has ever done because when you’re dealing with the public, you come across [rude] people every day. A customer came in once and ordered a complicated sundae (one that is rarely ordered so I had to use the guide). All of a sudden, the customer starts screaming over the counter, ‘Are you fucking stupid? How complicated is it to make a sundae?’ I ignored her and continued making her sundae, but she kept going. ‘It sure is taking you a while to make a simple sundae. I have somewhere to be, I can’t wait all day.’ I finally lost it and said, ‘You can make your sundae yourself because I’m not going to tolerate you screaming at me over the counter. I’m done helping you.’ I walked away, and someone else took over.” —Bela, current Dunkin’ Donuts employee
