Better than donuts...
In one town where I did a lot of industrial work, the local inspector had a heart attack (full cardiac arrest) on site one day and I was the only person who knew (or admitted to know) CPR, so I managed to keep him alive until the paramedics arrived. When he recovered and came back to work, my inspections with him were very "friendly", meaning that if he found something he let me correct it in front of him, or once even promise to correct it (which I did of course). When he retired a couple of years later, he apparently put in a good word for me with his successor and the good relations continued until I left the area.
It's not that I needed the help (
), but my experience in other areas with inspectors on industrial jobs tended to be contentious, because I felt for the most part many of them were out of their league, especially when it came to things like VFDs and Soft Starters. I had to spend a lot of un-paid time educating them (to be fair, this was 15+ years ago now, probably not still the case).
