at what point

[George Heagerty]

I observed a game last night where the head coach was ejected from the game. I couldn't hear what was being said but neither the coach nor the ref were arguing outloud . I could tell that the coach wanted to make her point and I belive that the ref went over to tell her she had lost the box as a result of a tech for protesting the other officials last call. I assume that she was still hot and continued complaining about the call(s). My question is as an official how much guff is acceptable from the coach in this situation. Should the coach be allowed to get in the last word and the official just walk away or should the official keep the upper hand?
