I recently blogged about an incident at a gas station: http://treygivens.com/?p=4613
As a basic rule of courtesy, I spend money in places when I stop to use the bathroom on road trips. I don't believe there's any moral demand for this nor do I think there there is any proper legal requirement here. I just think it's good manners. They provide good, clean facilities that happen to be convenient for me, so I spent a little money to repay them.
What do you think about this?
