Going to the supermarket in a foreign country is always interesting. One thing I observed and I was very puzzled about in Rome was that the shoppers would not touch the fruit and vegetables with their bare hands but instead put on a pair of disposable plastic gloves. Why on earth do they do that I wondered to myself? I had not come across this practise in any other country and I have been to and I have lived in many countries around the world. I saw this bizarre practise at every supermarket I went to, near the rolls of plastic bags to put the fresh produce in were a box of disposable gloves and a rubbish bin to put the gloves in once they had been used. I thought to myself that the supermarkets must go through so many boxes of these disposable gloves a day.
