It is this kind of crap that makes me want to neuter some people so that there lack of intelligence or they're being an intentional PIA, can't be past on.
A good surveyor should have one of these tools:

They cost about $12 dollars and test the GFI outlet or an outlet downstream. The surveyor who did my boat tested every outlet and found one bad GFI. I keep one on my boat as they allow you to analyze all functions and wiring of the outlet with one tool.

Every survey I get, there are issues that generate a similar desire for retroactive neutering.
My latest included a statement in the survey that "no mechanical inspection was done in this survey" which, naturally, brought on a request for a "Mechanical Inspection" before the next insurance anniversary. I then queried the insurance broker to see what such an "inspection" would entail, and how I would find such an inspector.
That resulted, after considerable back and forth, in a guy arriving at my boat and doing his "inspection". When I got his report, I didn't recognize my boat in it. Yet I had to write him a cheque.
Luckily, nothing in the report cost me more money.
This year, the insurance co wants another survey. My last was in May, 2018, so I queried them as to the number of years apart they require surveys. "5" was the answer. I then said I would be happy to get one before May 2023, to which the answer was, no, it has to be done before Jan 1, 2023. "that is 5 years"' I lost the ensuing argument, so am now scheduled to see the surveyor at my May 2022, haulout.
