When I was a student I used to work in a casino, ...
I'm a bit curious on what's your age by that time, as they did allow a student to work on a casino? AFAIK minors aren't allowed to work especially on that kind of environment.
AFAIK mostly on the other country if you are already at the legal age let's say 18 years old you can now work into a different establishment, still, if he is just an 18 below it's not good by the management, mostly we cannot give this any attention. Even there is an age restriction sometimes they have a "backer" or insider so they can easily access the organization and getting hired because they are already known.

I started gambling with curiosity, then after I tried to play with it either a casino or in house games, it was all begun with a habit only.
And I think there's nothing wrong with that as long as greed is not entering your mind. And to be honest as a gambler, it doesn't matter to me if there are materials or not just for me is only am entertainment nothing else.
Gambling is all fine till the time you are enjoying your game and not just running behind money or playing just to become rich form it. This is where we might start to complicate thing for our self and as a result it might become dangerous for us where we ay get addicted to it.
Well, there are a lot of people want to go to the casino to play gambling in different ways,
1. To enjoy - neglect the money.
2. To earn a profit - winning the gambling games.
Either on that still the best is to enjoy the game without thinking anything of getting lose. At the first place you already know the risk once you step in casinos.
