I'm in my third week as Editorial Officer at the Equality and Human Rights Commission, and I'm (hopefully) finally getting to grips with house style. I noticed on the style sheet mention of grocer's apostrophes, which are those random punctuation marks people just love sticking in words for the hell of it, you know like apple's 5 for £1 on a greengrocer's sign.
Our local grocer sometimes has some good signs on his fruit and veg. My favourite (although I noticed recently that someone has been at it with a marker pen) is his Coxy's apples. I always buy them - they sound so friendly.
