If you know people who work in a casino, it will be a bit easier. And especially people who work in management there, you have easier options there.
And it also differs enormously per country what the working conditions are. If you are good at your job in a casino, and you have potential then it is a beautiful world. That is, if you don't gamble.
Not all who work in casino is good when it comes to playing , even though you knew how it works sometimes it is too different between a player and a worker skills are much more needed when it comes to gamble, i work in casino as a poker dealer before this pandemic hits, and i tried to play with poker and it makes me so nervous its too different from playing than being an dealer with card it is like every time i made up some moves it make me sweaty, other's say listen to those who work are the casino they know better , we just told players to follow their gut's never chase loses there's always a right time to play and never get involve your emotion in gambling.
