Do you take responsibility for your losses, or do you play blame game?
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.
No matter who advises you to gamble, they are not responsible for the loss because you made the decision. Even though the advice was given, you have the right to decline it, but you still went ahead and gambled. Nobody is to be blamed when it comes to gambling; this is a decision made by people.
It is always good to gamble with money that you can afford to lose to the casino. In gambling, you either win against the casino or the casino wins against you. If the result is not in your favor, you just need to accept it. One of the things to learn in gambling is to make your decision, accept your loss, and never blame anyone, not even yourself, because you had the chance to make the right decision in gambling.
