Your vehicle is gas, all the pumps are wide open, and there is only 1 diesel pump on the very end. Seems that people with gas cars naturally gravitate to the diesel pump. Do you not consider someone may need diesel and you chose to use the only diesel pump for your gas car?

Trick question, you don't even need gas, you just want a roller dog. All the perfectly fine parking spots in front of the building are wide open... you park at a pump right?
