A number of years ago I was working a game with a first year D1 official (now works Con USA A10 and I think Big east), the coach for one team had been riding us pretty hard from the tip but nothing completely out of line to get him for. The ball is being inbounded by this official as the trail in the back court I am the slot right in front of this coaches bench awaiting the inbound and the ref yells up the floor to me
"Next time he opens his mouth to complain - you Toss him" loud enough for everyone in the gym to hear.
Coach sat down and coached his team the rest of the night and we had a productive evening.
Not necessarily recomended but it was effective that night.
