T'ing up a Coach....

On our way to our game yesterday my partner brought up 2 situations in which he was trying to get input about how he should have dealt with the situation. In both of these situations the coaches were upset with their teams and said nothing to the officials.

1) Late in the game team A downby a 2 or 3, A1 shoots a 3 and makes it and gets fouled. B coach jumps up yelling at B1 "How can you do that? etc..." and slams a clip board down on the floor so that it makes a very loud bang.

2) Team A was leading and has just giving up something like a 6 or 8-0 run and given up the lead. The last basket was an easy uncontested layup. The coach turns around after the play and kicks one of the chairs and knocks it down. Then proceeds to the end of the bench and sits down.

Just wondering if anyone out there would have T'd either coach or let it go and why.
