填空题 .Dear Sir,
    I have to travel every day from Jefferson Street to Times Square where my company is located. Two buses travel along this route: No. 1 and No.5. However, by the time No.5 bus reaches Jefferson Street it is always full, so it is of no use to me. This leaves No. 1, which sometimes has empty seats on it.
    The timetable states that there are buses from Jefferson Street to Times Square every ten minutes. If this is so, why do I have to wait half an hour for a bus nearly every day?
    The regulations state that if there are empty seats on a bus, the bus must stop at every stop where people are waiting. Why is it that half-empty buses go straight past me when I am standing at the bus stop?
    The regulations state that no bus may carry more than twenty-five seated passengers and thirty standing passengers. Yesterday I was the first to get off the bus when it reached Times Square. I counted the other passengers as they got off. There were about ninety of them.
    Clearly printed on the back of every bus is a sign that says "Maximum speed: 50 m.p.h." But sometimes some buses travel at an average speed of 60 m.p.h.
    It is obvious that bus companies have neither respect for the regulations nor consideration for their passengers. Can nothing be done about this?
