You know, I thought I was the only one who threw my stuff out or took it home with me. I always see everyone trying to leave the theater at once and not one person heading towards the HUGE trash bins outside the theater (and sometimes there's one inside as well) to throw their stuff out. I'd imagine it wouldn't be so bad. But I know people spill their drinks (and that has to be a real pain to clean). I always wondered why movie theater ushers have never snapped and went on a rampage! He/she/they/ would certainly get my sympathy.
