after the game

[stick]

This past Tuesday we did a boy's varsity game--a physical game at that. Lots of fouls--double bonus both ways early in the 4th. Toward the end of the game (home team winning) we had a skirmish break out after a foul. After that one of my partners went after a player (who got in his face), got in his face and almost decked him!! Luckily we calmed him down and restored order.
After the game we're in the a.d.'s office changing and the home team coach comes in (to call in the score to the newpaper) proceeds to tell us in a stern way how bad we were, how embarrassed we made 2 of his kids look by fouling them out, how we set a bad example for h.s. basketball, that we lost control of the game and everything that happened was our fault. Being in a no-win situation none of us said anything back to him so we left. My question is: is it proper for a coach to do this in the officials room because I always thought the officials room was kind of off limits to the coaches?
