The prices of movie tickets are bad enough by themselves, so I have no problem if people want to sneak in snacks regardless of the theater's policy. I realize they make most of their money on concessions, but really the prices are just beyond outrageous. I've never done it myself because I don't really like to snack at the movies anyway. If I eat, then I'm thirsty and need to drink. If I drink then I will very likely have to go to the bathroom and I absolutely hate getting up in the middle of a movie. I don't want to miss anything. Generally I dislike going to the movies though. These days I'd much rather just wait to rent/stream a movie in the comfort of my own home without dealing with other annoying movie patrons. And if I have to pee, there's a pause button.
