仔细阅读，选择正确答案。

Dear Sir,

I have to travel every day from Souk Road to the airport. Two buses travel along the line: the number 49 and number 16. But by the time the number 16 bus gets to Souk Road, it is always full, so I can’t get on it. I have to wait for the number 49, because sometimes there are empty seats on it.

The timetable says that there are buses from Souk Road to the airport every ten minutes. If this is so, why do I have to wait half an hour for a bus every day?

The regulations（规章）say that if there are empty seats on a bus, the bus must stop at every stop where people are waiting. Why do the half-empty buses go straight past me when I am standing at the bus stop?

The regulations say that no bus may carry more than 40 seated passengers（乘客）and 20 standing passengers. Yesterday I was the first to get off the bus when it reached the airport. I counted（数）the other passengers as they got off. There were 129 of them.

It is clear that our bus companies break the regulations and think little of their passengers. Can nothing be done to make your service（服务）better?

A. a message        B. a talk       C. a story      D. a letter
