Most London Blue Badge Tourist Guides have had clients who want to get a snap of themselves by a red London phone box, often with Big Ben in the background. It is almost a rite of passage for a visitor to London and so the red boxes at the end of Whitehall often have long queues of people waiting outside for the chance to take a picture of themselves.
