@futzle Switching off the outlets when the keycard is removed is fairly common in European hotels; I've frequently left devices "charging" when I leave the room, only to find them uncharged upon return.
@th @futzle@mastodon.social (they never actually verify the room key though so you can just use any old plastic card or probably even a piece of cardboard in the slot)
@f0x @futzle just like the UK power outlets don't verify that you're using an official BS1363 plug.
