ex-courier advice...hmmm
the day I went for my interview in London a courier mounted the pavement on Knightsbridge, went behind the bus stop outside the Lainsborough hotel and nearly hit me. Having lived in London for 3 yrs I realise most couriers will say "use any space available"! I may progress to this level in a few years but right now I'll take the other advice, especially in Bradford, where most car drivers are talking on their phone whilst waving to their mates.
