When I was younger, all I wanted to do is go to the casinos, even tho I didn't really blow much money. I was always not allowed or was removed from them due to my age. Now I can go because I'm past the age restriction, I really don't because I got bored of it and it's just a waste of time and money, also it puts me in a bad mood. 
For sure you will really got a bad mood especially if you only lose the game in the end.As for me,i seldom go to casinos only if i have invites from my friends.So far,i was not stopped or removed from all of the casinos i went.Knowing i'm in a proper attire too.But i have known a friend who had a fight with his co-player inside the casino.Until now he is still banned in that particular casino site.
