At the virtue of getting the unbearable situations to an end, the relatives broadcasts the chronic addicted gambler at all costs of gambling boards never to give him privileges to gamble in any of the Gambling arenas anymore else they (the relatives) would sue the gambling boards owner.
This is just how recklessness could mess your life of you can't take control to gamble responsibly.
I think this is becoming a norms in our society where people gamble recklessly and the relatives threaten the gambling operators for their ward irresponsibility. To me, this is purely unfair to operators and a trample to their business. These people are just running a business and should not be hold responsible for anyone's recklessness. Instead of threatening the gamble operators, they should rather caution their own ward who's addicted to gambling to stay away from gambling.
Where I reside currently, gambling operators are not allowed to open shop even after obtaining their license from the appropriate authorities but the community stop them from carrying out their operations simply because they believe their children will get addicted to it. Gambling is not for immature kids, it's for people above 18 years who are believed to have known what is good for them and which is not good. I have never seen where operators force people to play games, people willingly walk into their shops to play on their own. The relatives have no legal right to threatened the operator but he has the right to sue the relatives for threatening his business.
