I got a ping to pick up a rider and was there in less than 4 minutes. Well dressed 30's guy, with a large bag which I helped to load. At 3:30 in the afternoon I was sure it was a ride to the airport 15 mile away. Friendly guy, we had many things in common, and he had formally lived here. We got to the airport, I helped get his bag out, shook hands and wished him a safe flight. No tip! What's wrong with these people??
