Confronted by Coach after the game

[SmokeEater]

Well I finally had to report a coach last night. I T'd one of his players for contantly complaining about a call and he questioned me on the call. I explained there was no place for constant objections to our calls and then he challenged me calling my calls weak. So i said (as I walked away) If this continues Coach I can call another! No problems for the rest of the game, I might also add. I can admit that perhaps the T was a little weak and we could have gotten away with a warning. History has been that warnings don't work at this school, they just escalate the complaints.

After the game I exited the change room and there is the coach waiting for me. He starts in again about the call saying he talked to the player and the player said it was BS as well. I kept walking past him and said "Ok thanks Coach" and never even looked him in the eye. I kept walking right out the door as he said That explains it all and something like we'll see about this.
I called my assignor immediately when I got home to let him know about the confrontation after the game.

One thing I don't like is the Coach was waiting for me and also he would not let it drop after.

Question is, Faced with a situation like this, Does anyone have any other suggestions
