His just points out how little the people in office understand how things work.
After considerable investment in underground tanks, environmental monitoring, plumbing and pumps, not to mention pads and driveways and the building to serve all this, complying with environmental and a host of other regulations, gasoline is sold for a few cents per gallon above the anticipated price of the next load of fuel. Any profit is made on volume, but more so on the convenience store items, fountain pop, snacks and odds and ends in the store. That's where the profit is, not in selling gasoline.
Cut 10-15 cents off the pump price and the station will not be able to provide gasoline in a month or two, because they will not be able to refill the underground tanks operating at a loss.
