That's a pretty scummy thing to do, I assume that that person is a gambling addict because he/she tries to blame the casino for his/her misfortune. I feel bad for this person because besides being addicted, he/she also can't report a real scam or something illegal because no one is going to believe him/her anymore.
The worst thing is that one day, because of her addiction, she will be really cheated. But then, nobody will believe her because of her attitudes.
It's sad, when someone reaches that point.
Isn't that what I said in my previous reply? It is sad to reach that point but at the same time someone who reaches that point deserves arriving there since they lied over the same thing on their own volition. So don't feel pretty bad but they have to face consequences.
