This question has come up a couple of times already, but I’m not sure we’ve ever came to a consensus on it, so I thought we might benefit from a more dedicated conversation about it.  Hannah writes in…

This may fall into the Friday Free for All, as it’s kind of random:

I made my first visit to PURE today. I’m 33 years old and have never driven through a full-service gas station. I made quite the fool of myself by asking the attendant “so, what am I supposed to do here?” After a chuckle, he said nothing and politely filled the tank up.

Was I supposed to tip this guy? If so, how much? A friend of mine says no – that gas at full-service has historically been marked up.

I’m guessing I’m probably not the only one wondering the answer… can you clarify?

P.S. PURE is awesome. Full-service rocks. Forgive me if this question has already been answered in previous posts.
