I was sitting in the local Italian restaurant (they serve half-price pizzas on Monday) reading an article about Helmut Ruhemann, when a man came in with a delivery slip, looking as if he wanted to speak to the proprietor. I explained that I wasn’t the proprietor and he left. As the door closed, I realised that my mobile phone was gone. I said to a waiter that I thought that the man might have taken my mobile phone, so we both went out into the street and asked him. He had, and handed it back as if he was doing me a favour. He was.
