A couple months after 9/11, I was stopped with a penknife in my pocket at CLT. Security wanted to relieve me of it but having belong to my father, it had sentimental value. He suggested I take it to the US desk and ask for it to be placed in "will-call". I did and it was waiting for me when I got back the following day.

Two weeks later, it fell out of my pocket somewhere and I haven't seen it since.
