I've only been to the casino once ever. I didn't have a good time at all and I think I would pretty much have to be dragged there to go again. It's also pretty depressing to see all the desperate people there.
I don't know how to play a lot of the games so the time I went I ended up playing slot machines. After about 5 minutes though I realized I was just losing money so I quit playing and just waited for my friends to get done.
I think I am way too pessimistic to gamble. It's no fun if you don't think you will win.
