President Obama’s gaffe while toasting Queen Elizabeth II was not really his fault but it does make for a bit of a chuckle. The Royal band started their rendition of God Save the Queen during one of Obama’s pauses, rather than at the end of his speech.
He pressed on regardless, with a nice bit of backing music, then when he did actually finish, the Queen refused him a clink of glasses.
Blatant mistake from the band conductor; bit of a faux pas from Obama; and rudeness from the Queen. Maybe etiquette and politeness are not as closely related as I thought.
