[OHBBREF]

All personell at the table invloved in the scoring of the game are considered part of the officials crew. Now you could make the argument thatthe non official book is not partof that crew, but I personally would be stretching it.

I usually do not remove them the first time, in any game at any level.
I usually go over to the table at a dead ball and explain to them that they are part of my crew, and therefore have no opinion as to what happens on the floor, and if they want to express an opinion as fan there are the stands and if they want to be part of the team there is the bench. but if they persist on doing this at the table - the door is over there and that will be their next destination if I have to deal with this again.

works out almost every time. once in a while you get some one who wants to move, and by doing so there is a big target on their their back no mater where they go. the administrator has them as fan and the coach has them if they go to the bench.
