The first sign of irresponsibility is when the gambler blames others for his actions. if you can't own up to your decisions as an adult then you are not mentally mature and shouldn't be gambling In the first place. It's like going to purchase an item and after making use of it you go back and ask for a refund, it makes no sense at all. You cannot eat your cake and have it back, if you are not sure of staking an amount don't do it
Players may blame the casino when they lose at slots and then start accusing it of designing the games to take advantage of them. However, the games can only be controlled by the providers, and casinos can't manipulate them at least, that’s how it should be. I would advise such players to place bets responsibly, so they won’t have to blame the casino, except maybe the support team, since there’s always someone to blame if you want.
