One thing to know about Vegas....
Those fuckers do not like to lose. The comps are given to you when your winning because the odds are that the longer you play, you'll give it all back. Especially for high rollers.
The scene in 'Rain Man' when Hoffman and Cruise were piling up cash at blackjack and told to take their winnings and leave Vegas was very accurate.
It's no surprise that the city can afford to constantly rebuild and upgrade. Vegas always wins in some form or another.
But a hell of a lot fun, nevertheless. Got some wild ass stories, man!
