very vocal coach

[TC]

This is something that I did in a football game but the same principal could work in a basketball game, I think.
The coach was begging from the get-go. Towards the end of the 1st half, there was a call, against his team, by another official. The coach complained, as he had been all game and I ignored him, as I had all game. He finally got right next to me and asked, "Don't I get an explanation?!"
I calmly said, "Coach, when you complain about every play like you have been, no, you don't get an explanation." He was much better in the second half. Again, use with care, this won't work with every coach."
