Driving a car at a high speed along a highway seems to be fun. You need only to follow the bright traffic signs beside the highways and it will take you to where you wish. But to a London taxi driver, driving is not an easy job. A taxi driver has to have not only skills but also a good knowledge of the city of London, from the smaller road to the most popular bar around. He has to be at service of all kinds of passengers at all times.
A certain London taxi driver told of his job as follows.
During the night it is quite usual for him to stop two or three times for some refreshments (提神). He said, “I never drink when I’m working --- I would lose my license.”
He usually goes home between 2 and 3 o’clock in the night. There are times he has to stay longer and try to make more runs. He said, “That’s the worst thing about working for yourself. If you don’t make any money, no one is going to give it to you.”
London taxi drivers not only “take” but also “give”. Every summer hundreds of children from London will go for a day at the sea --- by taxi! Their rides are paid by the taxi drivers, and these all go to the “London Taxi for Underprivileged Children”. At the sea, they are met by the mayor (市长), and a lunch party is also held in honor of the taxi drivers and the children. After a happy day running around the sea beaches and visiting the markets, the children go home again --- by taxi, and free of charge (支出), of course!
