Some people will easily hurt others because of their frustrations and when you partner it with losing in gambling it will be more serious and others are gonna be in trouble while they have a kind of that person in their house or community. I remember when I had a friend and he was good at playing pools because that's one of the sports in our community that they make bets out of while playing. My friend was just a young guy and when he won big money from those big men, they made some evil plot against him while he was going home and they took his money from him after seriously beating him in the middle of the road and that's only one example of persons that are not supposed to be playing games like that because they cannot handle the heat when they lose their money.
Hmm maybe your friend didn't gamble in a casino. It could be some indoor gambling competition between him and the big men. If it's the later, then the person was actually gambling with hot tempered gamblers. Who can't accept defeat. Or maybe the other men are cliques of friends that rip off a winner's money. That's the risk of gambling with friends, off the casino settings. The casino is there to guarantee that players would be paid after winning. Without facing any dispute with fellow gamblers. However, the offline casino is also not conducive for gamblers because of such attacks. I'd say that gamblers who win early should leave the premises, while the day is clear. This type of attacks happens during the night hours.
[/quote]At least where I live pool bets are known scams and not one should participate in them, the scam is just a bait and switch scam in which the scammer fakes to play terribly and then gets in an altercation with another customer on a bar, then in order to settle their problems they play pool and make a high bet, and that is when they reveal their superior skill and scam hundreds of dollars out of unsuspecting victims, however if you were to win then they will follow you and rob you anyway, and for what I know this is a common scam all around the world so it is better to avoid those kind of bets completely.
