Even when I bet based on a friend's advice, and I lost. I still have to take responsibility for my own loss, not blame the friend who gave the advice. We cannot blame the casino, because they only provide the games, and it is we who decide to gamble.
Although some people, who I am sure are mostly non-gamblers, will blame the casino rather than the irresponsible gambler. We cannot blame anyone except ourselves. But everyone has a perspective on the situation they experience.
