Jeff Deck of Spokane, USA, has started a crusade against typos, misspelling and bad grammar. He visits shops, cafés and bars armed with Tipp-Ex, chalk and marker pens to correct the mistakes he sees on signs and menus across the US. He has been thrown out of bars for trying to correct an advert for "cake's", and gets all sorts of abuse for pointing out mistakes like "grocerry store" or "beefstake tomoatoes". Retailers get especially irate if he asks for a stepladder to reach a sign that needs to be amended.
