@TSO1973:
OK, I looked over the part of my OP that you bolded, and my other posts, and, frankly, I am stumped as to how feel justified in claiming that my story had changed. In fact, I don't believe you actually pointed out anything at all which made even the slightest hint that my story had changed, so I am left to wonder why you made that accusation without even such a slight hint.

For what it's worth, the TSA employee who called his supervisor when he recognized me at the end of the TSA line was not the screener nor the supervisor of the screener to which I referred in my OP, but was another TSA employee. The screener and his supervisor came later, and at about the same time.
