I have lost quite a few mortgage deals when the ea insists the clients have to use their own " advisor ". Along the lines of " it will be much easier and you will have more chance of your offer being accepted " This is illegal, but of course happens on every single transaction in most ea's offices.
Of course this tv programme will get the biggest w*nkers as it makes good viewing. I have worked with these types but also some genuinely decent people doing their best for the clients. For me I do however think, the profession can never be taken and indeed should never to be taken seriously...
