I was at a reception in an Officers Mess a few years ago at which Andrew was the guest of honour.
We were all standing in little groups as he made his way around the anteroom meeting evryone. One of my group (a navigator) decided he couldn't wait any longer and nipped off to the bogs.
Andrew appeared before he got back and, when he was introduced to this blokes wife, she was a bit befuddled and said,"Oh, my husbands in the toilet"!!!
Just after she said this, the wayward body reappeared at the end of the line and waited his turn.
Andrew was obviously listening to who he was being introduced to because when this blokes name was said, he quipped,"I hope you washed your hands!"
I met him in a previous era and I found that it was his toadying entourage who were the worst.
