That is an odd story. There is an inspector here in Mass (And I will name the town, Medford) that would not even test the receptacles. He would however make you test them while he watched. He will also make you remove the panel cover so he can look inside. While I do think he should be looking in the panel, I don't think it is unreasonable for the guy to turn out four or six screws. Particularly when an inspection appointment is "Sometime today make sure the cover is off the panel". Yea ok I'll just leave it on the floor, you come by when you get a free minute. [Linked Image]
