Not delusional, but sounds like you are used to using your brain. Which isn't all that common a trait.Is it me thats delusional? I'm trying to tow the line (that I broadly agree with btw) its just not sitting well with me!
I had a sparkie insist on strongly recommending an 'improvement' on a house I used to rent out. Didn't like the clearly labelled fridge/freezer ONLY socket which had no RCD (despite the then electrical regs having a clear stated reference to this being okay). People don't like seeing anything that is unusual. My thought was that it was for a specific purpose, the tenants understood the purpose, there were so many other available kitchen sockets that there was no reason to think the tenants would feel the need to use it for anything else, and the risk of power failure and food poisoning exceeded the risk of shock from a fridge which was hard to PAT test because pretty much everything was painted or plastic so it was a struggle to find any way of testing the earth connection. No exposed metal: no shock possible!
After a argument by email, we compromised on a weak recommendation for 'improvement' which I then ignored.
