Lol I remember when the Queen was in America, all decked out at a formal reception with George W. Bush, and he said something about her having previously visited America for our Bicentennial---in 1776! He made a comment that she gave him a look that "only a mother could give a child." She did joke about it though when it was time for her speech.
As to King Charles III and Inkwell-Gate, I though it was rude but sort of understandable.
Obviously he's spent 73 years being cosseted in every way and quite accustomed to the bowing and scraping that has accompanied his every move. So there was some of that.
But I also give him a break in that, as
@CSIDreamer said, this was and is a most extraordinarily stressful time for him. Losing his mother with whom he had a sometimes fraught relationship, knowing that his life is upended now with the burdens of kingship, having to hold it together while he simultaneously loses his mom and transforms into a king, doing it all in public, wondering what's going to be with his younger son and the Prince of Wales---IMO, to only snap once in public is forgivable.
I do hope Viscount Whatnot (TM
@Cappuccino) is not humiliated. At least he won't be beheaded.
