My pet peeve is when I mistakenly pull into the island that has the one diesel pump to fill up and someone pulls in behind with a diesel truck, edges as close as they can to my rear bumper, and revs the engine to try to intimidate me. I politely smile and wave to them. Finish filling up, go into the store and get an iced tea and a snack. If they have lottery tickets I might buy a few scratchers and scratch them off while in the store. Then use the restroom one more time and slowly make my way back to the car, wave and smile once again. I get in the car, adjust my mirrors and see what radio stations I can find. Then slowly make my way out of the station, all the while thinking "What a jerk that guy in the diesel was".
On the other hand, if one doesn't act like a jerk behind me, I will quickly fill up and leave so they can have the pump. You always reap what you sow.
