I've thought the whole shebang was moving this way for a while.
My reasons: Wtbts fears bancruptcy and has pulled in marketing professionals (in fact professionals generally)who have told them they are wasting their manhours with unsuitable (ie shy etc)folk going d2d when their time/resources could be more profitably spent volunteering in other ways and, of course - big turn here- working & DONATING if you cant do owt else!!
Also, going d2d pubs at risk of meeting folk like US who can easily show them proof that the WT is bs. At the carts (ususally)only interested/mad/desperate folk will approach.
I think the anti cold calling climate does not help either. Just my two penny w'th !
