Typical government employees.
I had to deal with both federal and state inspectors/auditors where I used to work. EPA, FDA, state versions of the same.
Man, I'd be embarrassed to be as clueless as many of them were.
I can remember some of them not understanding that gravity makes stuff flow/move downwards. Some of them not understanding that a couple 5 minute cycles at 580 F to 610 F not killing any bacteria that might have been on something prior to going into the first cycle, let alone the second cycle. Etc., etc., etc. Wanting filters on intakes (not understanding that an intake is designed to allow ambient air to enter a process and no process dust/particles are exiting an intake (we had an elaborate system of exhaust filtering/collecting for the process air exhausts). They felt like intake and exhaust both released particles to the atmosphere. I've seen those guys stick their hands/fingers into areas they couldn't see to feel around (I asked that one guy if he was allergic to bee/wasp stings and he got a funny look on his face and said, "How did you know that?" I told him I didn't but asked him how he could tell there was no bee nest back in that pipe he stuck his hand into. I had to turn and walk away to keep from busting out laughing at the expression on his face when he realized he was 6 stories up a large bunker complex with nothing but a narrow stairwell (no elevators) and he had no epi pen with him and he could have died right there that day.
I have no good memories of trying to explain common sense stuff to those folks.
