When I was down in Honduras, one of our favorite things to do when we were in the big city was to go see a movie. It didn't really matter what was playing, and they were mostly crap, but still. Anyway, I decided to go see a movie one night (Along Came a Spider, I think) by myself at this ratty three-screen theater around the corner from the usual budget hotels we stayed at.
I grabbed a seat in pretty much the dead center of the theater. I probably could've counted everyone in the theater on two hands. About five minutes into it, a guy in the last row aisle seat got up and moved a few rows down, still on the aisle. Five more minutes, he moved a few more rows down. Five more minutes, he moved a few rows down and was then in the aisle seat in the row behind me. Then he got up and moved to the aisle seat on my row. Then moved a few seats closer to me. Then another few. At that point, I got up and moved to the aisle seat on the row behind my original row to ensure I was between him and the exit. I sat down, and just as I did, the movie stopped. I waited a second, and suddenly the house lights came on. The guy got up and walked down towards the front of the theater, and went into the restroom (yeah, this place actually had restrooms inside the theater, along the wall).
At this point, I was pretty freaked out, and high-tailed it into the lobby. Since it was a later show, the lobby was empty. No concessions vendors, no ticket takers, no nobody. The sliding metal jailbar gate had been closed but left open a bit for people to leave. I ran out of there, back to my hotel around the corner, and went up to my room and chain smoked cheap Lucky Strikes until I was calm enough to go look for something to eat. At which point I realized it was so late that everything would be closed. So I just stayed in the hotel room and watched crap TV.
