discrimination

Today we went out to eat at a wonderful new place that opened in our area called Batten's Corner. It has really good food. While we were there we had a really great waiter. He was really really good. We saw something though that made me so mad. The people sitting close to us had the same great waiter but when they went to leave I heard the wife say to the husband about not leaving this wonderful waiter a tip because of the fact that he was gay. This made me so mad. What does the sexuality of this great waiter have to do with anything? He did his job and he did it very well. The husband said to her "yeah, but we shouldn't judge" and he put down one dollar for a tip. I had heard that things like this happen sometimes but to be sitting next table over when it happened.....It made me so mad I started shaking. He sexuality should have nothing to do with his tip
