Brother lost ID...

[Taso]

Me and my brother were going to head down to AC this week and he lost his ID. (Wallet was stolen actually, gotta love Philly) Obviously he's over 21, and we don't want to delay the trip until after he goes to the DMV, as that's a huge pain in the ass. What, if anything, will happen to him if he gets asked for an ID and doesn't have one? Will they take his chips away, or just ask him to leave? Any input, especially from floor people would be great.
