Not today but back when I was waiting tables at a steakhouse years ago we used to do all kinds of dumb stuff to keep ourselves entertained.
One thing we did was play the infamous "cat game" from the movie Supertroopers.
Basically we would follow someone out to their table and when we placed the customer's food down we would say something like "here's your strip steak meow".
Then, on a busy Saturday night, I followed a co-worker out and dropped of his customer's food followed by a "here's your chop steak meow".
Apparently, the guy thought I called him ma'am, made a big scene, called over our freshly hired new GM who ended up comping a $80 check because of his bitching.
I finished my shift and was fired before I left because he said he needed to make an example of me. In retrospect, I should have called the guy a chicken fucker.
Edit: yes I know I played the game wrong, hence the reason it backfired :)
TL;DR I got fired for playing cat game from Supertroopers
