Group of friends travelling from various UK airports a few weeks ago to an Alpine resort. One guy forgets to put his Swiss army knife in hold luggage. Not asked about it, gets through security and x-ray with no problem, and only realizes when he unpacks at other end. Led by his wife, he gets the rough end of the teasing. Meanwhile, travelling from another airport is a gay man who takes great care over his appearance. Security notice and confiscate a truly tiny pair of scissors. Sister of first guy is one of my friends, and says that nobody was impressed by the "lack of sense" shown by either security control.
