LadyJean may have come across the lady (her preferred term I suspect, but there may be others more appropriate) from Surrey (presumed) who entered into conversation (but see below) with a lady from Canada I was travelling with, in Dubrovnik.
My companion was buying things in the Old Pharmacy, and commented that she wasn't sure of the equivalent value of the euros.
"Typical of you Americans, the value of money doesn't matter!" interjects the Brit of whom I am ashamed.
My companion, in a voice dripping ice, "I'll have you know I am Canadian."
"No difference," retorts the upperclass chav.
People like that I have to apologise for, and that includes the people who "correct" LadyJean's vocabulary.
