I continuously hear call-in radio stations people calling in to complain that the shelves are empty. One particular station I was listening to yesterday a caller rang in bemoaning about visiting the supermarket and saying ‘there is nothing on the shelves’, “Nothing?” the radio presenter asked “nothing” they replied. When pressed again, the caller went into more detail. “Well they have no dry pasta, baked beans or toilet roll” was the reply. So, the presenter asked, “what do they have?” what do you mean the caller asked? Well, the presenter said a typical supermarket would stock thousand of lines; you have mentioned three so they must still have lots of other products on their shelves. What are they? “Do they have fresh vegetables and fruit, do they have pulses like lentils and beans?” asked the presenter “Yes, they do” was the reply. So, there is still plenty on the shelves, would you agree? “I suppose so” replied the caller.
