Re: Way Back...
"This is required in New York by code. At least one socket must be controlled by a switch in each room because there is no requirement that the room be fitted with light fixtures."
Aha!
Thank you for solving a mystery that has been with me for 20 years. Coming from Oz, where every mains socket has to have its own switch, I had assumed it was a cheapskate measure to save a few bucks on switches. If it had been in a private home rather than a hotel I would have assumed it was the work of an amateur electrician (my Grandad was one and not one light switch in his house worked as expected).
