Coach Belligerent in Coach's Meeting

[ReadyToRef]

This didn't happen to me but to one of the guys I assigned to a MS game. The coach is a real pain but can coach when he so chooses. In the pregame meeting, the officials ask the coaches the basic questions: Is your team properly equipped? Will they remain properly equipped throughout the entire game? Will they show good sportsmanship throughout the entire game? Both coaches answer yes to these questions.

When the official asks "Will you display good sportsmanship throughout the entire game?", the coach replys "It depends on how you do tonight." When the question is repeated, he replies, "It matters what calls you make." It is only after the question is repeated a third time that he finally answers yes.

How should an official handle this situation? I appreciate all replies and help.
