Apparently, that station doesn't get used very often. If it did, wasps wouldn't build a nest there. They don't seem to build a nest overnight.
I started my pickup on Tuesday for the first time in about two months. Needed it to tow the trailer to a distributor to help my brother pickup (literally) a ton of fireworks. At the gas station, I found a wasp near the filler neck, and shortly after that, noticed a wasp nest built right by the gas cap. Guess I need to sell it or drive it more often...
