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

Here's the situation: A1 is dribbling the ball in his frontcourt. B1 knocks the ball off of A1's leg and across the half-court line; A1 first to pick it up - by rule a backcourt violation (which we called correctly). About a minute later B1 attempts a pass to B2; A2 deflects the pass into back-court which B2 retreives (no violation - we made no call). Not knowing the rules, Team A's coach was screaming-mad as Team B is running their offense after recovering the ball. My partner, Trail in front of Team A's bench, blows his whistle to stop the play, and turns to Coach A and begins to explain the backcourt violation rules and the differences of the two plays. I wanted to tackle my partner right then and there. I expressed my extreme displeasure at half-time and told him "don't ever do that again!"
Although this incident happened last season, I've already worked with him once this year....he called a charge in my primary when I had a block (fortunately I held my signal so nobody knew we had a "blarge"). I'm scheduled to work with him on a big rivalry game in Feb. - not looking forward to that......
