You know I work for a newspaper and media company. And that I work nights and take the company transport home after midnight. So it stands to reason that the people who get on the transport at that time of the night are fellow journos, the marketing and admin people having fled the building at 5pm. And journalists, whether print, online, photo or infographics, are people whose jobs require observation and sensitivity.
So why is it that night after night, there are people giving directions to the Malay bus driver in Mandarin?
