I had a bad experience at MCO last time. I took my shoes off right before entering the line at the security check area (to save time and not hold up the people behind me). The sneakers I was wearing had laces and a velcro part so they weren't coming off easily. The agent made a nasty comment about me dragging my germs all through the airport. I had on brand new white cotton socks, and the sneakers were new for the trip. We're talking a very short distance here. I wonder what her problem was?
