I had to go through a security scanner the other day, not for flying, just a low level government building. The detector went off, I guessed it was my metal collar. I was pulled aside, arms out, hat off and after using the hand scanner, the Officer said 'I need to see your belt Ma'am '
I thought, 'OMG, my belt!!!'
I told him I didn't have a belt on my jeans.
'You need to lift up your sweater Ma'am...'
I wanted the ground to swallow me up. I discreetly showed him my hip band and explained what it was. He was more embarrassed than I was at that point and let me pass.

Any of you folks have embarrassing stories?
