Unusual But Now You Know

I found this label on door at a doctors office and thought it unusual.  Never seen a bathroom sign that used two separate words to refer to or identify a "Restroom" before.  Perhaps, it's just me, dunno.

Seems, perhaps, to be a reference back to the late 1800, when there were rooms designated for 'rest" and back then they did not include a commode.  The toilet requirement followed years later.

"Restroom, also rest room, rest-room, 1887, "room set aside for rest and quiet" (in a workplace, public building, etc.). As these often later had (or were required to have) accessory toilet-rooms, by 1930s the word came to be a euphemism for "lavatory, toilet."

Here I was ready to make fun of the sign, rather I learned a thing or two instead.
