@eurocelticyankee,
I've told this before, but I am reminded again -
Many years ago and far away in California, Prince Philip was visiting our medical center, and was taken by the oh so eminent head of our department to visit my lab, at that time a bit of a light in the mist of medicine as a new kind of special lab for certain diseases. I saw them coming down the hall, and quickly went to the ladies room, there to stay for, oh, ten minutes or so. When I came out, Dr. X had no doubt given his little speech and I was free..
Rude of me, looking back. It was a mix of m'irishness and probable dignitary phobia. That was likely '66 or '67. Would I do that now? No, I don't think so. Now I'd be more curious to watch the two in action.
