Haha, I got some funny and sad stories about Vegas, the time I won gloriously the first night I was there, then the trip home 4 days later I had 8 bucks and some change in my pocket.
Saw a drunk sit down at the Blackjack table next to me late one night, he was drunk and from all appearances wasn't that great of a player. He was betting 100$ a hand and losing every freaking time. The female Asian dealer didn't look to torn up about taking his money.
Also had a friend go into a local Indian Casino once and won a little over 20 grand, he bought himself some new clothes, a steak dinner and the rest{you guessed it} went right back to the Casino. Not making light of his addiction but gambling addictions are real and sad. Some people have no control.
