The bottom line is that casinos don't take care of their employees, and it's a shitty system. What kind of business provides no real product, then expects losing customers to pay 95% of their employees' salaries? It's bullshit.
The last time I played at a casino, I put $3 on a hard eight for the dealers. It hit, they took down $30, and I cashed out immediately. I took my even amount, $500 or $600, whatever, threw them a dollar chip that I had left, and one of the dealers said, "gee, thanks for that dollar." What a fucking asshole. If I had bet the hard eight for myself, and then gave them $30, they would have been happy. But they don't consider it that way. Why the hell they would feel like I owed them that much anyway is ridiculous. If I ever opened up a casino, I would pay my employees a fair salary and not allow tipping.
