If they ask a question on a public-facing device, they must expect a response. Right?

The brass fitting seems intended for a braided hose leading to a nozzle, but there was no corresponding floor drain in the room. I’m sure the shutoff valve in the bottom elbow was turned off.
Back in the motel, I attempted to plug in my charger:
The currently trendy black-on-black design scheme doesn’t work well in the low-light environment of a motel room. The white plastic tabs in those USB sockets were the only visible parts of that whole assembly.

I’m guessing the plumbing is to fill a mop bucket or one of the Zamboni-like floor machines.
The default hotel for my semiannual big-city trips hasn’t received the built-in charger upgrades yet; I think it’s a few years from getting the remodel/renovation ordeal. I carry a power strip with USB chargers along with a wall wart or two, but I can see the temptation. :)
USB C has an optional mode where two properly-spaced sockets can provide near-sinewave 120V to a power plug.
Ooooh, and if you jam a widowmaker plug into the sockets, you’ll charge the USB-C devices!
