The needs of an electric charging station vs a petrol filling station are quite different though. And also consider that electric vehicle users can charge overnight at home, so those people driving 50-100 miles per day may not need to use a charging station at all, apart from long journeys - which is likely to impact the favorable locations significantly. Even with super fast chargers, you're looking at 15-30 minutes for 100-200 miles of range, vs 5-10 minutes for 400-600 miles of range. Assuming a limited amount of space for vehicles, a traditional liquid fuel filling station can probably handle 4-6 times as many customers, so the electric charging station will need more physical space to serve a similar amount of customers. Users are going to want to do something for that time, so that convenience store will probably expand to add sit down food/drink facilities. In short, I suspect that in 10-15 years time, filling stations will have evolved into something completely different. Or maybe electric charging will be a bolt on to anything that has a car park, and dedicated charging locations will be relatively rare.
