I was in the casino. The bettor standing next to me said to reach in and grab your chips. I won. The dealer paid me, too. All I know is I walked out of the casino $400 richer. This was in Cincinatti.
He wants to sell his method, he is a scammer. Dont trust him.
Years ago, I used to frequent a casino which was run by a Greek family and one of the nephews worked as a croupier. He was a bit of a rogue and many times he would leave my losing blackjack bet on the table or even pay me out on a stand-off. I used to see him the bookmakers all the time and always used to pass on a bit of information if I had any. I suppose it was a kind of you scratch my back and I'll scratch yours scenario.
As far as genuine mistakes go, I can remember a mate of mine getting paid out on a bet that he never even made and wasn't at the table. We walked up to the table and the croupier who was busy paying out just stacked these chips and said ''there you go!'' Obviously a case of mistaken identity.
Or a test of chharacter that doesn't cost much .. if anything at all.
Oh well, then he failed the test of character but he did exit the casino rather sharpish with an extra £250 in his pocket.
