The rules have obviously been relaxed. In Laker days, staying in the airport Excelsior Hotel in MAN the requirement, at about 0200, not much before, was to run naked from the room, touch the front doors and back to the room. Least noise possible in order not to attract the wrong sort of attention. Definitely no banging on others doors. A 'runner' from the previous sortie would be at the door to check!
