What is the worst banking experience you've had?

"A while back, I was at a restaurant where the server seemed incredibly unhappy. She asked me if I wanted pepper, and I said yes. She aggressively cranked the pepper grinder, and it broke and spilled peppercorns all over my plate. She looked at me angrily, said, 'now look what you've done,' and took my plate away. I waited another 45 minutes for my food before we just asked for the check and decided to leave. I'm not sure what was happening behind the scenes there, but she was clearly unhappy. I don't know if it was her job or something else, but I wasn't going to add fuel to the fire. If she didn't like her job, it showed, but her attitude made her situation so much worse. It's unfortunate. But, on the upside, 'now look what you've done' has become a family inside joke."
