Justice,
I have no problem with how you handled the situation. You deserve to be allowed to eat in peace and quiet. But. And there is a but...

My guess is that the young men had expected to have won big bucks and scored some hot babes by the time they found themselves with empty pockets and just themselvers for company in a coffee shop at dawn.

That doesn't excuse their behavior, but also complicit is the meretricious come-on of Las Vegas, the city that promises everything, delivers little, while taking as much as it can.

Las Vegas bases its economy importantly on and has as its raison d'etre the sexual objectification of women as much as gambling. The smarmy wink and meretricious promise of The LVCVA's "What happens in Vegas..." is just one example of a decades old promotion of the city as a place where one's carnal as well as cash fantsies will be fulfilled. When the scam is finally revealed to the victims, trouble often ensues.
