I would not ordinarily tip a gas station attendant for filling my gas tank. The reason I tipped the attendant in my vignette I shared in post #22, is because I asked him if he was willing to fill my tires with air at the air pump that is meant to be self serve (you pay for the air), and it was not part of his job to do this for me. It was a favor and he was willing to do it for nothing. For that, I tipped him.
