Sir. Disappointed to see you don't tip your chauffeur. Of course this is not compulsory and is down to your own discretion. However, I would like to point out that UK chauffeurs are only paid the minimum uk wage. Also, they are not paid for any part of the journey that the car is empty. So in effect the driver could drive many miles/hours to collect you for nothing. Gratuities are a very important part of the chauffeurs income.
