A Voyage in the East

A rhetorical question some would say, but the best answer that I have is three. One to actually pump the gas. One to push the button on the fuel tank so that the meter is reset, and one to watch and then take the payment from the driver. In fact, everything in China is incredibly labour intensive. Go into a restaurant and have 6 people serve you. Or more likely one person serve you (some of the time) and 5 people watch this person work.
