Coach out of box

[lukealex]

In my game yesterday, I had a coach come out his box and to halfcourt (short court, halfcourt was maybe 5 feet from end of box) and tell me "come here, I need to talk to you about that call." I called a foul on his player he didn't agree with. He had been complaining most of the game, out of the box, and on the floor. I gave him the stop sign, told him thats enough, and he turned around and went back to his bench. The more I think about it, I probably should have given him a T.

What would you have done given different severities of the situtation?
