In Whitechapel in London's East End, last week, I had a job to do about 2 miles away in the city. It took almost 2 hours to get there.
There'd been a few serious accidents and so on plus all the money being thrown at tarting the roads up for the Olympics and all the roadworks, etc. and new traffic schemes designed to hold up all the traffic designed by idiot council twats, etc and so on.
Then another 90 odd minutes to get to the next job about 1 mile away. I had 6 jobs that day and done 2.
