Is the unofficial Book considered Team Bench Personel?

[WAZebra]

Is the teams book person sitting at the table considered part of the team bench personel? After a game last night my patners and I were discussing the visiting teams book person. I hadn't noticed anything to be concerned about but one of my partners did. My partner said that on more than one occasion she made a very dramatic response to a call that is unsportsmanlike behavior. I know in the past I have had to just tell them no more etc etc., which I may not feel like doing anymore. The question is can you T her like someone on the bench? Do you just remove them? What about if it was the official home team book person at the table instead of the visiting teams unoffical book person?
