A new welcoming sign has been put up by the chimps in charge of such things at King’s Cross Station. Is it being too picky to expect the correct use of apostrophes? Or should we all just not bother? Reader Xan forwards the other one, even more horrible, from Tesco – or Tescoe’s – who really should know better. I wouldn’t mind, but it’s such a hilariously simple rule: If it doesn’t abbreviate or possess, there’s no apostrophe, ever.
