What's the point of tipping a casino dealer anyway? Unlike in a restaurant, there's nothing a casino dealer can do for me above and beyond what he's paid to do ordinarily that isn't illegal.
If you feel that someone doesn't deserve a tip, then don't tip. That's the genius of the American way. The European way is idiotic for it automatically includes the service in the price of the meal where customers will have to put up with what ever service the business chooses to hire. Chances are the servers they hire will be uncaring, unproffesional and unmotivated, for the expense of hiring good waiters would only cut into the owner's profits. Service is about carng and those that take a job for a set wage obviously don't care about what they earn or what level of service they give. I've heard the service in Europe is deplorable. You wait forever just to get the waiter to take your order and you wait even longer to get your bill. I'll take the American way where what you give dictates what you get. While the current situation in America does have it's problems with businesses stealing their employee's tips, eventually this problem will come to a boil and be dipensed with once and for all.
