Unsolved problem

Susanne Ho of KMB (South China Morning Post, November 4) clarified that RoadShow surveys asked interviewees whether they liked the programmes on buses. It is still not clear how the 1,000 interviewees were sampled.

Was it a random sample? Did the sample include passengers who loathed on-board TV broadcasts? How could the survey ask passengers who did not watch the TV broadcasts 'whether they liked or disliked the programmes'?

If the surveys did include customers who felt bus TV was an infringement of their freedoms and an exploitation of their captive audience situation, how could RoadShow improve the programmes based on the survey results?

Customer satisfaction is paramount to firms operating in a free market.

In contrast, despite continual complaints about bus TV in the past two years, franchised bus companies still have not solved the problem to the satisfaction of many passengers. This calls for more stringent regulation from the government so as to better protect public transport commuters' rights and interests.
