Tipping for some people is just a way to show how great of a person the tipper is. Same with refusing to pack a healthy lunch. "Look, I am too cool to carry my lunch" I am no fan of the new generation but at least they aren't wasting their money and are trying to eat healthy. Us older pilots generally are fat and still in debt (look around). Keep tipping $5 every van ride and spending $25 for a fat laden lunch, just remember it doesn't make you a better person. Stop being a tip Nazi if I don't tip the van driver who never left his seat, it's not a taxi cab, it's the shuttle that takes you to the hotel that you then check into and pay to stay there. Van driver does not = waitress.
