Forgiveness is a great thing, we should all have some of it in our hearts, but sometimes you have to forgive and then forget.
I mean if someone is guilty of using a gun to shoot someone, you might forgive them and thats fine and dandy, but if you forgive them and then give them another gun you are an idiot.
Same case here IMO, we should fogive some of these casinos, but after strike one, two, and three, its time to forgive them and then forget about them.
