In my "retirement" specialty as a transportation professional (taxi driver), I took a University of Maine Professor Emeritus of Blah Blah to the airport in November, on his way to Vallhalla (Paris) for the big conclave.
He made the mistake of engaging, and in a snotty way.
It ended when he said, "You won't think you're so smart when the ocean rises and there are no more beaches." I said, "When the oceans rise, sir, new beaches."
He never spoke the rest of the way.
I assisted with his bags and he tipped well.
I could only smile.
