Reminds me actually, yesterday while hiding the pile of Daily Mails (better known as the Hitler Digest in these parts) under the Croydon Advertiser I noted the headline was about the glory of overthrowing EU tyranny by point crown signs back on pint glasses. Done by Boris, of course.
I don't actually know what this symbol means, maybe the Queen spit shines every glass, though I expect they're made in France anyway*.
*I can't have been the only small child to have up-tipped his glass of school-issued drink to see the glass was made in France and to be filled with vague exoticism, that there might be a world beyond those mounds of coal spill. OK, I possibly was.
