The degenerates of ThugCity have been donating their money to the casino for decades.
Thugs take no interest in gambling. They know the risk and reward, and prefer to up the stakes.
Upon owning a class 3 or higher weapon, Thugs can attempt to rob the casino for 4000 $BILLS, but if caught, they will be arrested.
Cops may stake here as well (required to own a class 3+ weapon), where they will receive medallions for catching Thugs.
