Let's say for argument's sake Trombonist, that you're in college in NYC and you and your friends decide to go spend a Friday or Saturday night seeing a movie. The ticket to a regular movie (regular movie meaning one that isn't in IMAX or in digital projection or 3-D). The ticket costs about 12 dollars and fifty cents in NYC for a film. Reason why I didn't include digital projection or anything like that is because movie theatres charge more for those. Now, since a lot of people get popcorn or snacks at the movies, and since they are over priced, when all is said and done you would have spent at least close to 20 bucks that night. There is theatre in New York that you can see for 20 bucks.
Hell, there are even a couple of Off Broadway theatres, such as Second Stage and Playwrights Horizon that sell tickets at 15 bucks a pop for students.
