Why do the cops always camp out at the movie theaters?

Obviously you've smoked too much already if you cannot figure out that the theaters pay to have them there.

Well obviously that's why then. The movie theater managers have complained to the local police department that you stoner's are constantly sitting in the parking lot smoking weed so they're putting a stop to it. Get over it.

cops can't camp on work hours, besides wouldn't they go camping in the woods or desert?

why don't you walk around a corner to smoke or sit in your car or even better don't,

You answered your own question sport.
