It's a gas station and I can't get emotional over a gas station. My response is almost always "confident" and "comfortable" and occasionally "impressed". In the comment section I usually mention ample or limited parking for the c-store and a 2nd sentence commenting on a full or limited assortment in the store. If the restroom is pristine I mention that. My rating for the average station is 7 and I have gone as low as 5 for a really bad one, but that is rare. My highest rating is 9 for a really "impressive" station. I don't know how useful this type if information is to the client as it is subjective.
