It never ceases to amaze me, that people are puzzled and upset when you ask them if they can prove residence or prove ownership. Obviously we’re often called to liberate items that obstinately remain chained up and to liberate people from wet and windy porches.
I had a call from someone whose 21-speed, alloy-frame bicycle was chained to some railing in a local park the key to which had been lost. “Can you bring some proof of ownership please?”, I said. There was a frosty silence, followed by “I can assure you it’s mine.”
