Funny that you should ask. Being tableside, we met just off the baseline outside the lane. I went to his side and asked in a low voice if he knew the player was passing. He ignored me, and continued walking to report. When he confronted me after the game he also mentioned that "the coach heard that!" which makes both of us look bad. I said that I knew the coach did not hear me (the coach was at least 15 feet away and I was speaking so no one else could hear me), but he said "you can't know that!" Simply put, I spoke in a fashion (low voice and unobtrusive) so spectators would not think I was showing him up. He took offense anyway.
