Fleecing passengers

Hasib, Khulna University
Recently, I purchased a computer and took it to Khulna from Dhaka as I'm a student of Khulna University. After I reached Khulna Sonadanga bus terminal, I had to face transport problem. I was looking for a helping hand who could carry my computer but I didn't find anyone. So I had to carry the heavy monitor and CPU to a rickshaw. But suddenly a man came from the terminal and asked for money! He claimed that every passenger had to pay it at the terminal. I was finally rescued by a friend. My question is, why should the professional extortionists be allowed to target innocent passengers?
