I was thinking the exact same thing! I was wondering though was the hooker at the bar working for the Casino? Cause Ray told her about the card counting thing and when he goes back to the bar to meet her, Security is waiting for them. Just curious.
That's exactly what happened. And it happens all the time in Vegas. They have hookers and other ladies who flirt with the card counters just to get information out of them.
There's also Private Detective Agencies kinda like the one Lil B is in that are hired by casinos to keep tabs on cheats. They lump card counters in with them.
You have to remember one thing.... card counting is legal in the United States. A Supreme Court case ruled that it is legal because it doesn't "alter the nature of the game". I agree because it is not a form of cheating.... it's simply using mathematical skill to give you a bigger edge in a game of chance.
