Once more and I'll give up.

It has nothing to do with being cheap. It is simply a different cost structure. You may have noticed that restaurant meals are less expensive, generally, in the US than in Europe. The cost structure permits this. Of course, after you add your 15-20% tip to the bill, the difference becomes less.

If you owned a restaurant and your food was as good as the competition, but you decided to pay your servers $10 an hour (plus tips), you would have higher prices and fewer customers. 2 years down the road, you're out of business.
