Casinos know man likes beauty, so they offer beauty dealers on card games, like blackjack, baccarat.

So people feel happy even if losing money, because they love the beauty dealers.
But still if you keep on losing there, no matter how beauty the dealer you will still get angry with everything. And i dont think that it will become addiction to you because what really affect the addiction is only the feeling want to recover everything, meanwhile beauty is just some extra addition for gambler for having fun
