Letter: Runaway trolleys

Sir: The writer of Outlook on 28 October saw his pen rather ran away with itself like one of Sainsbury's trolleys before the pound coin trolley-release mechanism was introduced to encourage customers to return trolleys after use. Previously, local streets were littered with discarded shopping trolleys in roads, on pavements and in car parks, to the inconvenience of the public and with consequential costs of retrieval to the store. A pity more stores do not have this system, which has been normal practice on the Continent for a number of years.
