Most interesting. I wouldn't have thought any of those little details matter, so I guess I am not representative of the market.

I never shop at the gas station convenience store (unless traveling and in need of water). I pick a gas station solely on convenience factor, ie closest to me on the correct side of the road. The only criteria I have is that I do not use gas stations (Arco) that have central payment islands vs pay at the pump.

I'm pretty amazed anyone cares what gas station they go to, and actually pick one over another.
