Prolly need to tell him to shut his pie hole and when he gets into the game, he can call it any way he pleases.
He should know better than to talk unsolicited to the refs during a game. He's table support - he has his own job to do. If he wants to talk after the game fine, but you made a call and you really don't need someone else making the whole crew look like a bunch of idiots. Then you get people questioning every call - asking "are you sure about that? Maybe you shold ask the table.".
Situations like that tick me off - bringing crap into the game.
