Recently I went to see a (fairly serious) movie at a fairly isolated multiplex in Northern CA. I paid for my ticket then strolled over to the restroom before the movie started. A woman was holding the door open, which I found odd; inside the restroom a poor man was standing at the sink, water all over the floor, with reams of paper towels covering his body. He was screaming and moaning. The woman kept leaning her head into the bathroom as I did my business. "Are you done, Frank, are you done?"
I walked slowly across the lobby to my theater, and sure enough, the woman and her charge came bounding beside me and then ahead of me into the very same theater I was about to enter. Before they disappeared through the door, the woman leaned to "Frank" and said, "now don't scream through the whole movie this time, Frank."
Without having to think, I immediately turned around and walked into another theater, where they were showing the Wallace and Gromit movie, which I had wanted to see anyway. I sat down in the middle side section, in a place with very few people, and as the previews began a large family group wandered in, walking a very large dog. The family (of course) sat right next to me and the dog, who was very wet and very smelly, was "given" the seat next to me. It didn't have a "seeing-eye dog" identification; it just looked like a big wet family dog. It smelled like wet spaghetti and dead rat, and I could see bits of dog hair floating around in the air.
I stood up, apologized to the family for momentarily blocking the the previews, and walked all the way up to the back of the theater, where there were lots of empty chairs. Thirty seconds later a group of six teenagers creeped in at the bottom and then stomped quickly all the way up to the back, taking all the seats directly behind me and kicking my chair, hyperventilating, shouting, giggling, talking on their cell phones, and making a general ruckus.
I literally ran all the way to the front of the theater in the "neck pain" section, sat down in a heap, and enjoyed the rest of the movie without incident, though I did have a cramp for the next few days.
