What's with the police of Nepal ?

They have to respect all citizens of Nepal. One time I was at airport to receive my father. Suddenly a police rushed at me and pushed me from the side and I almost hit the floor.

I later found that the police were pushing people who were there to get people to take their taxi or hotel service. That is also unacceptable but doing that to some one who was not even doing that is the incompetence of the Nepal police.
