And I walked into my double feature Geostorm movie and there was no one else in the theater so no tickets were sold. That worked for the first 20 minutes until suddenly the audio shut off and then the screen shut off and the lights came on.
Same thing happened to my nephew and I a few years back. The movie theater near my house is almost always a ghost town, save for opening day for some movies, so it isn't a big surprise when we find ourselves as the only two in the room for a film. When they stopped playing our movie and turned on the lights, we went to the front and told them to either give us our money back or start the film again. They were not too thrilled with the first option.
