((Yeah, I'd guess that we did))
Silently curse self for not bring sufficient firey stuff, then finish moving bottles and take a quick jaunt around the party, picking up empty glasses and scoping things out.
Ask Mr. Brooks if he has ever worked this kind of gig before, how much work we should be expecting, if the DJ is any good, and if he usually likes to snag drinks in between songs. Harmless questions. Also wear a polite smile.
You float between some of the tables, collecting several glasses. Not many people are here yet, so you ask Brooks a few things. "I do this sort of thing regularly," he begins, "Some A-list celeb throws some party, and Clay always seems to be involved, and every time he's got a new ridiculous haircut and seven different broads with him. Usually these things are fairly busy affairs, but we do manage to get the glasses back quickly." You then ask him about Clay's drinking habits. "Here's a hint. Keep eight shot glasses and a bottle of vodka under the bar. He seems to always get drinks for his group. Not a bad tipper, either, but god that hair..."
Upon saying that, a rather pompous looking man with a shiny white quiff walks in wearing a small leather jacket and tight white jeans... and seven scantily clad women. The ladies sit down as the pompous gent gets behind the decks and Brooks hands you a vodka bottle.
