I don't think that casino staff could help you and offer any more insights than anyone else. People either have strong or weak characters. Those with stronger characters will realize that they have a problem and stop. Weak-minded people will keep going, trying to profit where they can't, and dig their own graves a little bit deeper every time.
Gambling is a leisure activity and should never be considered as a job or a safe way to make money. The hardest thing to do is to recognize you have a problem. Once you do that and stop lying to yourself, you can start looking for a way out. Many gamblers, unfortunately, never arrive at this stage and keep telling themselves I am fine, I don't have a problem.
