This is very complicated. Most restaurants employees, if they have more than two brain cells will treat you decent because they are supposed to do that. They put on a fake smile. Bad or good service depends a lot. I don't say that looks don't influence the way they treat you, or the service quality, I just say that just because you're ugly doesn't mean you will get bad service. The opposite is also valid, there's plenty of good looking people that had bad service at restaurants, lol. I say this, because I don't want some lurkers to think that just because they get decent service at restaurants, they are better than us. Although I have to agree, if you're constantly getting bad service in restaurants, good or bad, you should start asking yourself some questions
