What's the worst/ nastiest thing that ever happened to you while eating in a restaurant?

I’m sure by now everyone’s heard of the guy in my city that sent his steak back while dining at a Texas Roadhouse and the cook got so pissed off he hide pubic hairs in the steak and served the guy. The customer took the steak home to eat, found the hairs and is sueing the restaurant. The cook got jail time, I believe. Has anything similar or also nasty ever happened to you? If you’ve seen the movie ‘Waiting’, you’ll agree anything could be in our food when eating out.
