Has this ever happened to you?
You are on a date.
You are at a movie in a multiplex. Everything seems to be going quite well.
You excuse yourself and exit the darkened theater to visit the restroom. When you return to your seat, your date is gone.
You look and look. No luck.
What the?
You go back out to the lobby to see if your date might have gone for a drink of water or whatever while you were away.
Strike two.
But while in the lobby, you realize for the first time that the movie you have been watching is showing on two screens, side by side.
Having already looked in Theater A, you try Theater B.
Happy ending.
