After finally managing to successfully pay for some gasoline I hurried back to my car and opened the little door to the gas cap.
Why on earth a wasp would want to build a nest inside the little gas-cap door on my car was beyond me, but there was no way I was going to stick my hand anywhere near him to twist off the gas cap. I looked around for something to swat at it, then realized in order to hit it hard enough so that I didn't have to worry about it surviving and stinging me, I'd have to hit it hard enough to more than likely break off the little door. Not a story I wanted to tell the guy at the repair shop.
What to do? I was running really late by this time, and stranded until I figured out a way to get gas into the tank. So I lifted the gas nozzle, activated the pump, then held and aimed the nozzle at the wasp as though it was a pistol. BANG! (or maybe GUSH!) Instant death. At almost $3.70 a gallon, I figure that wasp cost me about $1.
