"Look, I and my wife are ordinary people. My daughter and her husband invited us for a a Christmas dinner. We expected to have a glass of wine or two so we splashed out on a taxi to Letchworth. As always we spoke to the driver and learnt quite a bit of his background. This made the journey pleasant and we learnt a little more about the situation in his homeland. A very interesting and knowledgeable driver. Unfortunately we had no money with us to provide a tip but if the money goes to the driver I will leave a tip"
