Wanting to simplify and expedite my LHR-->LGW transfer around 11pm late one night last Nov, I had decided to take a taxi. I went out to the taxi area at LHR and was quoted a very high figure (which I wish I could remember). The dispatcher noticed my distaste and suggested I negotiate on my own a better rate with the numerous, idle cab drivers standing around. In so doing I landed a fare of about 60% of the original quote!
