I had a similar experience at LHR T1 recently involving one of the ICTS girls, who, upon seeing her initials on a couple of the stickers said "Oh, I've had you before". Of course, I had to ruin it by saying something crass and idiotic - "not yet luv, but you've screened me before". She was not amused.
