Shop in Morrisons like I do then. You don't see many other customers.Families who met other families supermarkets by chance. They promptly form a ring in the main aisle to bring each other up to date on their tedious lives and, even when other shoppers have managed to get past one side of the ring, still stand there chatting inanely while the shopper tries to get past, rather than moving slightly to let them get out of the circle.
