For father, I can say that he can gamble out his money according to his wish as he knows what he is doing due to his experience. Also, that particular money belongs to him, so we can't impose any restrictions upon him for spending his own money, but as far as they're concerned, teaching the value of money to the children is significant. Also, as per Nevada's state laws, he was underage and legally isn't allowed to drink and gamble, so he was not supposed to do that; the responsibility lies with the parents to prevent him from performing any illegal activity.
