In a perfect world, the officials are strangers to everyone in the gym except each other. Most of us do not work in a perfect world, especially at the lower levels. Dealing with the people you know, even close friends, is sometimes the worst part. Be prepared to go home thinking: I can't believe he said that. I can't believe they got that upset. I can't believe I had to have Grandma thrown out of the gym. etc. etc. Even more importantly, be prepared to quickly put all these things behind you and move on.
