Front desk work could be done away with mostly by electronic systems (most of the time when I "check in" it's just picking up a ready made room card as I checked in online). You could even centralise the "talking to a human" part in a call center operating a number of hotels, who delegate to staff on the premises (house keeping, maintenance, room service, etc). Of course luxury hotels will still have humans.
Fuel pump operator hasn't been a job in most Western countries for decades, as you just pump fuel yourself (and often even pay at the pump). Is "EV charger operator" a job?
