I am actually more curious about the rules of casino employees allowed to gamble or not in the casino where he works, unfortunately did not find an answer regarding this rule.
It is indeed difficult to just work in a casino without becoming a gambler, whether an active gambler who does spend quite a lot of gambling or just a seasonal gambler, because gambling is a very tempting activity, especially since he will see people who win every day even though there are more losers.
There is no other way to survive in that job by controlling yourself because without self-control all the money will be spent just for gambling no matter how big the salary or tips are if you continue to follow the desire to gamble then all the money will be used up and maybe even go into debt, if you still can't control yourself then looking for another job is highly recommended before finally falling into an addiction that can endanger yourself.
