My Father is a Black Cab driver and I can confirm that they are scum :)-D Seriously, just get into a Black Cab and sit down and then tell the driver where you want to go. If his light is on (it will be if he has let you in) he has to take you, by law, anywhere within a 6 mile radius of Charing Cross - I think all of ED falls under that. If he starts to make a fuss, tell him that you know the '6 mile rule'... if he still continues, tell him you are about to take his license number and number plate and shall complain to the Public Carriage Office first thing tomorrow. I have never had a problem and I have been wasting money on Black Cabs to Dulwich for far too long. Simon
