Price of gas $$

We have bussiness dealings with a couple of C store owners. When they buy high $ r/e, they must have a store of addequate size to support the cost of land/building. County zoning can be a pain in the ***. Sq ft of land to sq ft of store. The gas does not make up their profit profile. Gas brings the customer in and selling store stuff makes the $. Or so they tell me.
