If you were the casino manager would you fire the casino worker for interfering with your business or would you ban the gambler from visiting the casino?
Banning the gambler won't do anything good to his gambling habit. He will just go to a different casino or gamble online. What I will do is I will invite a psychologist to the casino to talk to him abiout why is he still gambling everyday despite of his losses and his wife just gave birth. If that doesn't work then I won't be able to do anything for him anymore as it's not the casino's concern why he continues to gamble.
As for the casino worker, that is not enough reason to fire him. He is just concern to the addicted gambler and did not do anything to the casino's profit
I agreed to invite a psychologist to the casino so he could consult about his gambling problems. I think it will work if there is support from all parties, especially him, who is willing to open himself up with help so that he can cure his addiction. This will be an attempt to help her heal and she will see that she is not alone in solving her problems. If this works, I think he can get better soon because he will surely realize that everyone is still supporting him and wants him to get better.
