It’s easy to forget the biggest museum in the world is free and never closes. The city, its streets and the people who bring them to life are everyday objects with a thousand stories to tell. What matters is the way we see.

We were handed a plastic carrier bag (to look inconspicuous, of course) with binoculars and headphones. An oddball Doctor Who-looking figure sitting in Wetherspoons came over the line.

A chugger had water thrown in her face. Then the offender went on strip down to something racier and later dance in the Clarks shoe shop window. Was it was set-up?
