Isn't this just the stupidest reason not to give her her winnings?
this is pure fraud, the lady won for real and honesty but the casino owners don't want to pay a penny of the lady's winnings because they definitely don't have as much money as the lady won. supposedly for a country that legalizes gambling, this kind of thing can be reported to the police because all the evidence has been collected and there is no fraud that the woman is doing, the one who cheats is the owner of the casino.
How could they do this to her?
As I said, casino owners don't have that kind of money so they never have any intention of paying out the big winners. it's just their excuse that the machine is broken, fraudsters should be punished and their gambling business should be shut down.
