ABSTRACT
It is easier to select a specific grouping appropriate to a particular topic – for example, early risers, commuters, children or lorry drivers. If the question is to do with an increase in petrol prices, one will find motorists, together with some fairly predictable comment, on any garage forecourt. Similarly, a question on medical care might be addressed to people coming out of a hospital. Incidentally, many apparently public places – like hospitals, shopping malls, schools and even railway stations – are in fact private property and the broadcaster should remember that he or she has no prescriptive right to work there without permission.
