Well, I did it once by accident

, here where I live, the bathrooms are inside the movie theater beside the entrance, and they don't check to see if you have tickets.
after seeing a movie I went to the bathroom to "dump my load", and when I got out, a crowd of people came towards me(who turned out to be the next showing people) and I had to go with their direction, so I went with them to the movie theater seats again

, and so I was able to watch another movie for free.
