it is usually that they are not deep but there are so many of them, in one station you could have 3 for Gasoline ( 87, 89, 91 octane ) and 2 for diesel ( off road & on road ) and one for kerosene all in a small 1/2 acre lot and then most of the room is taken up by the giant store to sell sugar and salt to the patrons . The machine needs to have an incredible reach out not down .
