What is the most frustrating thing your partner(s) have done?

2nd year guy...Mr. Hotshot...went to three camps and the NASO convention over the summer...calls a player for a foot OOB on the baseline from C. Not only was it not his call, but she wasn't even close to the line--I was looking right at it. Instead of making him look bad by "overruling" him, I just employed the "quick travel" on the other team ASAP stratagey. At half...we had a discussion!
