Ehh... I think the kids are all right. It's obviously a shit show, and I wouldn't be caught dead there, but so long there is no concern about serious injury, and the golf is able to continue at reasonable pace, I say let them run amok in peace.
It's gauche, sure, and it could be managed better, at the door and behind the bar, but I think having one event for the folks in the tuxedo tshirts is good for the game. Let's not take ourselves too seriously. It's obviously very popular.
