The last time I saw a Greengrocer's apostrophe was on the "sale" signs of a major department store. As my eyes rolled, I noticed that the only two signs that featured the stray apostrophes were "Pen's" and "Book's" - both products aimed at the sort of anal nerds who notice such things. Amusing coincidence, or deliberate manipulative marketing?
I fled the store before the subliminal messages in the background music could worm their way into my head, and hummed loudly to block them out as I went. And I needed that new fondue set, anyway.
