The metal polisher

Soul Man was intently brushing away at the big metal bowl outside a restaurant in Kensington. I did a double take then went back to talk to him. He said I could take his picture if it was in "Good faith". I asked him what he meant by that and he replied that he was happy as long as I didn't say anything bad about him...

... why would I?

I told him I thought it was very enterprising to walk from business to business with his trolly of cleaning equipment looking for work.
