So far I've resisted the temptation to do my supermarket shopping online. Some of the stories of online shopping over Christmas have further convinced me that it's better to do one's shopping in person. My favourite cautionary tale involves a Tesco customer who ordered a walnut loaf and received instead a whole octopus.  It worries me that someone who sees little difference between an octopus and a walnut loaf is at loose in society and possibly driving a car.
