FOOD MART at 915 Camino del Rio South, San Diego, California.

Very competitive prices. It sort of holds a monopoly in the area, being its the only gas station surrounded by 5 hotels and a dealership. But didn't exploit the fact that they were virtually the only game in town.

Gas buddy app did say there's another gas station within a mile that was cheaper but in reality it's 4 miles away. Too inconvenient to drive 12 minutes out the way to save 20cents on the gallon, especially when not traveling in the direction.

Very quick. I was in and out.
