If any hapless passenger dares ask a simple question, like who is in charge, he will be referred in sequence to an Attribution Meeting, a Review Meeting, a Level A Meeting, a Level B Meeting, a Contract Managers' Meeting, a PPP Board Meeting, a Senior Representat ive Review, an Adjudicator's Review and a punch-up between Stephen Byers and a judge. After that he can choose between Gandalf, Merlin and the Wizard of Oz. Either way he will still be standing at Oxford Circus station.
