Oops! 1,500 taxi drivers in Guangzhou lined up in front of the designated service stations to have their taximeters repaired on February 29, the leap year day, after they found a bug in chips caused a malfunction to the meters.Since the “leap year” factor was not considered in the design, the taximeters did not Feb 29, which comes around only every four years. So, when the clock ticked past midnight on February 29 morning, the meters malfunctioned.The cab drivers thus could not work for the whole early morning, and demanded the compensation from the meter manufacturer, Hua Gang, too.Later in the afternoon of the day, the Hua Gang company promised to pay 300 thousand yuan to taxi drivers affected as a compensation.
