Sir, you cannot ring that thing in here. Do it one more time, and you'll be escorted out. Now, you can surrender that thing to me, and I'll dispose of it. You won't get it back. Or, you can sit on it the rest of the night. Any noise at all from that thing - accident or not - and you will be shown to the door, and it will be confiscated for scrap metal recycling. Clear?
I need you to verbally acknowledge your understanding of what I've said to you... OK. Best you stuff that thing with a hankerchief or something. Just a clank, and you're history. OK. Enjoy the rexst of the game, sir.
