When is enough ... enough

IMO, you need to address it in some manner; doesn't necessarily equate to giving a 'T'.

I had a coach Saturday who was getting on my nerves. Whining the whole 1st quarter even though his team was up by 10 AND the foul count was in his favor. After the 1st quarter when I went to the table he started to approach me about "contact on both ends, blah, blah, blah". I cut him off before he could finish and told him that "this is not a conversation we are going to have". He tried me one more time in the 2nd quarter on block call he didn't like. I ended that conversation ratherly tersely. Didn't hear from him the rest of the game.

You need to remember you are the authority figure in the game. Sometimes you just need to take charge.
