What inconsiderate pricks. This is such a new-money move. Everyone gets it, you have money. It was probably clear to them from the hefty bill and the amount of booze you bought. So pull out a credit card and pay for it like a civilized adult. Only reason to pull this maneuver is if you're flying off the government gird, you're on a road trip that involved murder and a buried a body, or you're a showy f*cking a**hole. Video taping it tells me these guys are the latter.
