I have been flying for 167 years and I have NEVER EVER seen a frog in a gas pump. When is the last time you saw a CFI check for frogs? You are all lying and need to find Jesus!
But seriously, I have a 35 gallon gas tank at home with “aviation” Mogas that I use for my plane and I have to make it a habit to look in the filler line to check and make sure there is not a paper wasp nest, or bat, or whatever. It helps the the hose is clear, but the metal nozzle could hide something. Of course my gas jugs also have filter screens on their filler necks, so most would get filtered out before it get into the aircraft tank.
I have never taken the gascolator apart myself (always the IA at annual) to see how much dirt it traps and how much is making it into the tanks over a year. I did just remove and clean a gas tank and it’s finger screen was clean with only the usual amount of crud in the bottom of the tank.
