It always used to horrify some people when they saw plate switches
in bathrooms. Others still get upset at non-isolated shaver sockets
in rooms that only contain a basin and toilet.

On a similar note, I've met several people that are uncomfortable about
a switched socket left switched on with nothing plugged in. They will
go round the room checking them all.

Some people seem to overly absorb the "electricity - dangerous!"
message as a child, fearing walking close to a consumer unit etc.

Daft it may be, but if it affects a sale...
