What are your pet peeves about other officials?

[WVJD]

Last night my partner showed up two minutes before tip off, I had already fulfilled all of our administrative duties. He walks in with a pair of shoes under his arm...I get nervous but he assures me that he knows what he is doing because he has 30 experience in another state...he then tells me he doesn't have a jacket. Next he asks if I have a whistle for him. Unfortunately the game gets started and things went down hill. He is way to good of an official to get stuck with sub varsity games.
