I managed a 24 hour Hess gas station right before and through the Odd/Even crisis of the early 70s (I got stories of my life being threatened). I was there when Unleaded hit the stations (so we had Regular, 100 Octane and Unleaded). On holiday weekends, we would pump 3x-4x the total storage capacity out of that tiny station.
The District Manager would come into town unannounced, and sit in the parking lot across the street and do a 10 Car Survey. We had to clean all the glass, the headlights, the sideview mirrors, tailights, etc. We also had to pop every single hood (or make the attempt), and had a quota to sell at least one quart of oil/tranny fluid for every 100 gallons of gas we pumped.
On the upside, our Manager's Meeting was at a Playboy Club in New Jersey. Can't do that anymore!
