We had a crazy experience at MCO about a year ago We were traveling myself, DH, DS, 2DDs, and my father-in-law (who was CLEARLY the Grandpa in the bunch) My FIL has had two hip replacements, so he carries a medical card explaining that. Made no matter to the TSA, they hauled him off to a room, checked him head to toe and swabbed his hands and in his ears. Even looked in his mouth. Fortunately, he was a good sport about it, but my DH and myself found it a bit ridiculous - he was wearing a mickey shirt and hat and was travelling with his family. And dont get me wrong, I understand they are doing all this to keep us safe, but they we very abrupt and rude to him.
