Today our waiter was Aki, from Japan. He'd been trained in Austria and, like Abdul, he intended to go home after a stint at the Savoy. How did it compare with Austria, I asked him? "Well here it is a lot more international. The staff here are from many different countries," he replied carefully, with a little bow. As we sipped our tea, the ever-attentive Aki hovered close by, ready to top up the cups. With afternoon tea at £23 a head, the clientele can expect certain standards. Would he be able to keep my tip if I put it on the credit card slip, I asked. He assured me he would.
