Interestingly enough, I've read that in Vegas, hotels have breathalyzer's in the lobby, only $0.50 to make sure you're good to go, or not, I guess.

Of course, leave it to vegas visitors to come up with the idea of seeing who can be the drunkest according to the machine, by the end of a night's debauch.

Needless to say, as a hotel owner, I'd be leary of encouraging/participating in bets involving a frequently fatal to OD on substance like alcohol.

This is probably why I don't own a hotel in Vegas, and never will =p
