Just left him babbling
 

First half, partner calls a foul & home coach wonders what happened. Partner gives him an explanation and coach is still asking. Partner lets him know it's time to move on. Coach now very loudly asked what happened. What happened was a T. Partner reports foul & I go to let coach know he must now remain seated. He continues to say all he did was ask what happened and that the T was bush league. I told him he asked, partner answered, asked him to stop conversation....coach would not shut up. So, I left the area so we could administer the FTs. Did not want to machine gun him and he was fine the rest of the game. Probably because he HAD to be.

Would anyone have handled this differently?

Priceless !!!
 

Priceless. I nominate this for the Forum quote of the week.
