This topic reminded me of the good time that I have at work.
To all of those who do it, next time you go to the cinemas, just think of people like myself when you're stomping the popcorn into the carpet, then shooting up and leaving your siringe un-capped on your seat for a 15 y/o to find, then urinating in the cup you just drank out of (because the toilet is a huge 50 paces away) and ofcourse leaving it in the cup holder for us, and vomiting all over the entrance to the cinema. Then come out after the movie and say the the print quality was bad and get free tickets to do it all again.
Ahhh, the world of customer service. But hey, it creates employment, and it's a small price to pay for what essentially is a good casual job.
Although I would expect things like this would happen in aircraft aswell, but I always clean up after myself.
