Whistle in mouth?

[Rich]

I don't know, actually. I'll see what I do tomorrow night. I'm pretty sure I do in case I need it, but there are times I'm talking to a coach and holding the whistle in my hand during a live ball, so who knows?

I do remember once a coach was asking a respectful question while I was the C tableside and I was responding quickly and I had to abruptly put my whistle in my mouth and call a foul on his player. Instead of reacting angrily, the coach laughed and said, "that's what I get for interrupting you when you're working."
