‘Faraday Avenue?’ The driver of the articulated lorry leaned down out of his cab and handed me a delivery sheet, pointing to the address at the top. This seemed an unlikely destination for a pallet-load of freight. The driver couldn’t say much more than that in English, and my Bulgarian isn’t much good either, but he at least managed to explain that he had a delivery for an address on this road. Except he didn’t. On closer inspection, the delivery address was another Faraday Avenue, on an industrial estate, the other side of the city!
