Assistant coach went after my partner today

[Refhoop]

Here's the situation:
4th quarter of a 2 pt. game. Team A is leading by 2. My partner gets a common foul on Team B in the back court - under one minute. Head coach (great all game), does a little dance and runs to his seat. Assistant coach (JV coach and a terrible one) also jumps up to dance after the call. Partner goes over and warns: "coach I suggest you get your bench under control".
Head coach: seems embarrassed and nods in agreement...
Assistant coach says: "We're not talking to you" in a contemptuous tone.
Partner: Whack!
I totally agree with the call - though as the L, I couldn't hear what the assistant coach said.
Team B goes on to lose by 8.
Buzzer to end game sounds and this assistant goes after my partner before we leave the court and follows us into the hallway. The game management person is nowhere to be found...
Eventually this ___ coach gets under control - my partner gets into the dressing room. I go back into the almost empty gym - get the scores for both teams back in there: whack and eject the assistant. In our state, he can't sit on the bench for the next varsity game...
What say you!
