At my work at the time (pre-pandemic) we used to have an EV valet - attendant would take your car, park it and then move it to an EV spot when one opened up, then put it back into normal parking - you would get a text with the location on each move.

It was quite nice and let me focus on work instead of worrying about charging and only initial paperwork (we had QR stickers on the car and keychain QR).

That's about the only time I've used a valet regularly.
