HUH?? I don't understand your question. I can clarify MY mechanic and that is a coach is yelling for a timeout, I look and verify he wants one and is authorized to have one, hit the whistle and call the timeout. If the words "time out" comes out of that coaches mouth and I see and hear it. He gets the timeout and he can deny that he called the timeout for the next 30 or 60 seconds.
