Movie Start Times -- a theory

As I mentioned earlier, I hate how movies are scheduled at the Multiplex. My favorite theater has 30 screens, but only a couple of start times. There is a mad scramble at 6:45 to 7:15 in the parking lot and concession stand.

I had wondered why the theaters are all doing it. My new theory is: it stops screen jumpers, those cheap people who pay once and go to a couple of movies. If only they could get a couple of those nerdy ushers to check tickets.....
