In my (midwest) experience maybe in cities 7-11s are primarily convenience stores, but once you drive out into the suburbs/country they’re always gas stations. Until I started living in cities I wasn’t even aware there _were_ convenience store 7-11s!
The weird ones are in the lower density American suburb/urban transition area where many of the 7-11s are setup as if they could have gas pumps but don't and act as drive-up convenience stores/small groceries.
