Capitalism

I remember walking around the city, and walked into a bar to goto the bathroom. Bartender made me buy a beer. I didn't have a problem with that. Just buy a small item for common courtesy, or if they are busy, just leave a buck or two.

People open up businesses to make money, so they are helping you, help them. I once gave a lady at a fast food chain $20, because I had to use the bathroom really bad. They were to busy for me to order, but it was worth every cent to use their bathroom that day.
