I haven't seen the movie yet, but it is definately on my "Got to see" list.

In addition to this thread, maybe it would be interesting to hear from people who have worked in "Food service" or "Bartending" and hear some of their "Revenge tactics".

I had one particularly HORRIBLE customer on a regular basis. They would complain about every little thing... "The soup is too cold", "Why doesn't this taste like last time" and of course, during an unusually busy lunch hour, "What is taking so long". I probably could have ignored their complaints, if there was at least a hint of a tip. One day, just for kicks, I took back a soup that was "Too cold" and poured 2 garnish cups of HOT Gardinera *sp* into the soup. As they sucked down the soup, I tried to hold back my laughter as I watched them turn red.
