Spotted in Cardiff City centre by an eagle-eyed Welsh speaker:

If you’re an English speaker you’re told to look right, but if you’re a Welsh speaker, you’re told to look left! Wait a minute. Is this a plot to rid the world of the last few polyglot Welsh (in which case Cardiff, the most English city in Wales, probably isn’t the place to perpetrate such a foul deed), or, more likely, is this a cunning case of Welsh language fascists finding the perfect scheme to ‘accidentally’ maim the saes?
Or is it just that someone, somewhere screwed up?
