Finding yourself on a rush hour tube journey, especially on the Northern Line, can provide the most interesting experiences of human behaviour. It is not difficult to discover the value that many morning commuters place on “The Metro” (Free daily newspaper in London) as opposed to the other occupants of the carriage. People are happy to move and be a little squashed up to the point where they are still able to read their paper but woe to the uninitiated who attempt to prevent the reading of the daily gossip columns. The unread paper is more valuable than the other fellow commuters.
That is until the pictures have been viewed, the news items skimmed because then the paper is tossed away, its value gone, and then it becomes an issue for someone else.
