It most definitely wasn't worth it, in the end I was in negative funds for just my fuel bill, they were giving us such low rates it was almost impossible to make any money.
I'd leave the house at 5am get to the Isle of dogs for 6am then sometimes could wait 2 or 3 hours for a job to come through, but the catch was we couldn't sign on at home then ride in we had to ride to the Isle of dogs first and just wait around. Quite often I was actually effectively working for nothing
