Waitrose in Towcester has closed down for a week to make what it describes as ‘a final few touches’ to an ‘exciting’ refurbishment. We will see just how exciting this is when the store reopens this weekend with its ‘improved customer toilets’, ‘improved café’, and so on. But forgive me for being a little sceptical, for normally the main effect of a supermarket ‘refurbishment’ is to disorient shoppers.
