It's usually newbies that will rather shift blames on the casino instead of taking the responsibility for their gambling decisions and results. The blame they shift on the casino probably makes them feel satisfied or less frustrated but at same time it builds up problems for them such that they would not want to learn from their mistakes and it is very bad character to exhibit.
Not just newbies but most gamblers blame their losses on the casinos when they lose big instead of accepting defeat and putting taking the blame for gambling with the amount they could afford to lose, it's no longer new that casinos do not force people to gamble and the rules is very clear the casino doesn't force anyone to continue gambling when they are losing but the greed of wanting to win back the amount that is lost has always been the reason why gamblers end up losing so much in gambling. Gambling is risky every gambler should be mindful of the mistakes they make and take responsibilities instead of shifting the blames to the casinos.
