On a recent rainy afternoon I took a No 101 bus from Kai Tak to Western after seeing a friend off at the airport. The fare was not excessive, only $6.50 for a cross-tunnel trip. However, regardless of the cost, I think the Kowloon Motor Bus Company should pay better attention to hygiene on its old vehicles. To my dismay, as I was staring out of the window, I saw at least half a dozen small cockroaches moving along the window pane. Looking around, I found that some others had already crawled their way on to the passenger rails. It struck me since it was an air-conditioned bus, there was no reason why there should be a pest problem. What would the scene be like on a non-air-conditioned bus? Would it be even worse, with unclean seats and an unhygienic environment? I and my companion had to move to other seats to avoid the unexpected nuisance. We were lucky that the bus was only half-full. Still, I was made to wonder: has this profit-making bus company failed to maintain hygiene on its fleet? NAME AND ADDRESS SUPPLIED
