In most ordinary airports, train or bus stations, if you leave your luggage unattended it will be removed and maybe destroyed; but at Paris Orly airport, it will be removed and systematically destroyed. None of that feckless, willy-nilly destruction for the French – they can leave that to the British luggage handlers.
Speaking of British randomness: security at London City airport consists of passengers and staff wandering back and forth through a metal detector, sometimes with two people going through in both directions at once, and someone from the cabin crew flipping through your passport just as you board the plane.
