In the very first This Old House, Bob Vila was trashing the innards of a house, and took a part in the demolition. He took a steel crow-bar, jammed it behind some base molding right next to an outlet box - with the plate still on IIRC. he yanked and the whole thing came apart, with the outlet box trailing BX cable. I was all but screaming at the TV.
Next week, Bob was standing in front of the camera with a stack of papers in his hands saying something like "A lot of you wrote in about me pulling the baseboard with the outlet in it . . . ." Turns out, they had checked off the air and the line was dead. Or so he said.

I remodeled a huge part of my 100+ year old house in Illinois - family room, kitchen, lavatory (deconverted an illegally converted bathroom) and back entry way. Stripped it to the studs, and rebuilt the whole thing, took out curtain walls, everything. I had a friend who was a union electrician help me with the electrical (he worked on the International Terminal at Chicago's O'Hare - this guy was good). Short story - the electric inspector was visibly pissed when he did the inspection, he could not find anything to report other than ONE loose switch box conduit nut (yeah, code, we had to use EMT). I'm talking 220 to the built-in range/microwave, plus separate lines and switches to just about everything else - lots of work done, and he could find nothing other than the nut.
He then growled that I had to add an outlet where none was indicated on the plan - and this was after drywall had been added - and put one on the finished end of the island. I asked him in all innocence why this had not been caught when the plans were approved. He was even more pissed. Shoved the plans at me with a violation notice, growled "Do it!" and left.
Of course, that was better than the inspectors in Chicago who were all on the take.
