I filled up my truck yesterday (diesel) then while the truck was filling up I walked to the pump on the other side and filled up my gas can with gasoline. I swear someone honked at me. What's the difference? Either use two pumps and leave the station faster or stay at the one pump longer. I prefer to get out out there and go eat my lunch.
I pay with a credit card. Surprisingly it works. I think they charge a pre authorized amount before you even pump.
