I often stop in College Park to get gas. I note the following: the station I get gas at has 6 pumps. Typically, there are 1-3 other people stopping to get gas when I do. It takes about 5 minutes to fill my tank. I usually wait until I need about 12-15 gallons but I suspect that I other folks are more risk-averse than I am. I will assume a typical fillup is about 10 gallons. If I assume in the 5 minutes I am there that 2 people fill their tanks then in an hour my station will sell about (60/5)x2x10gals=240 gals in 1 hour. So in a 10 hour day, they would sell ~2400 gallons. I expect that in the evening and during the night, they will sell less -- say 1/2 as much. This means in the rest of the day (the remaining 14 hours) they would sell ~1200 gallons for a total of 3600. In one week this suggests a total of between 20,000 and 25,000 gallons.
