in this particular place in the US where i live, supermarkets are in competition, 2 supermarkets are in the same intersection and another 2 supermarkets are in another intersection 1.5 miles from the former one . moving east just 1.5 miles is costco . another 1.5 miles is another huge supermarket. moving north 1 mile is walmart . etc etc. this does not include gasoline stations which doubles as a convenience store ! You are very wrong my friend or u are seeing the rural portion , like the mountains of tennessee !
