This is great advice for not only casinos, but life. Too many people blame others for influencing their actions instead of blaming themselves for blindly following people without thinking. You don’t have to gamble. I would say a majority of the times I’ve been in a casino I didn’t gamble. It isn’t hard.
They are just immature and think about that there's easy money on gambling. Reality slaps them when they lose big and here they are blaming the casino for bad decisions they made.
If they just let them selves be more mature and have discipline towards budgeting also other aspect towards gambling for sure that they won't act like a cry baby once they lose. Gambling is fun if they just know the consequences of their possible action. This is the reason on why people should know first if they can able to lose the money they use and if they can handle emotionally if there's something bad happen and if they know for their selves that they can't lose their hard earn money then better for them not to gamble at the moment.
