How’s this for a sign that the speed culture is on the defensive. A while ago, McDonald’s started offering healthier food like salads and bottled water. Now I’ve just heard that any customer who orders an Asian chicken salad gets a free yoga DVD. Could there be a more absurd paradox? A company that built its fortune on the drive-thru Big Mac encouraging punters to chill out in the Lotus position. I suppose the upside is that this underlines how far the Slow revolution reaches. But I’d be more impressed if McDonald’s took the really bold step of handing out DVDs of Morgan Spurlock’s documentarySuper Size Me.
