My favorite was some time ago at Kaitak watching a young Chinese guy go through the staff security checkpoint ahead of me. He went "beep" so the girl carefully waved her wand over him, carefully checking each item that went beep.
Satisfied that he had no illegal knives, nailclippers etc hidden he was sent on.
I was pissing myself because the items he carried that did go beep included an UZI machine pistol, a sidearm and grenades!
Luckily he was security, I wonder if she would have stopped him taking in a screwdriver?
