Growing up, I would have understood "gas" to mean gasoline. But having lived in many places where the word is used differently, I was really unsure what they were talking about for most of the story. A note to the author: the story would have been much clearer if you said "sold gasoline" and not "served gas".
The story was perfectly clear to me, but then again I live in the south. And most gas stations around here sell food and often are the best food destinations around for certain things.
