They are not going to ask you to play

Went to the Tour Championship today. Had a good time, but here is one thing that just makes me wonder what people are thinking. I saw spectators, marshals, and tournament officials all wearing golf shoes. I've been to a few golf tournaments over the years and have seen this at all of them. What are these people thinking, "Someone might drop out and they are going to ask me to fill in?" I just want to go up to them and tell them that there s no way they are going to get to play today. At least I know which idiots to avoid.
