Jerricho...
Oz and V1OOPS, what you fail to mention is that a large percentage of London Taxi drivers are some of the rudest individuals you will ever come into contact with.
I invariably fail to mention things that I've never observed or heard about before. In fact, the only problems I've ever had with cabs in the UK was when I was stupid enough to use one of those mini-cabs in London.
They're a really poor excuse for a taxi. More like the Sydney cab drivers in that they don't know where they're going and hardly speak any English. They're complete pirates too.
