Do gas stations double as convenience stores in USA? I ask as an european because here, snacks at gas stations usually carry a hefty markup in price and usually we go to minimarkets.
Yeah, most of them do double duty with a shop inside. The snacks and drinks usually have a high markup, but there aren't a lot of free-standing minimarkets except for a few 7-11s.
Then there's Wawa, which is the weird outlier. :) I think they sell gas as a side business. The inside is all about getting food.
