Punjab Roadways — misbehaving conductor

I am person who travels regularly from chandigarh to garhshankar and every time while purchasing tickets when my turn comes for ticket the conductor always makes me to wait and every time the behavior of conductor is rude. They always harass the passenger for the change... This is the main bus stand and they are saying the things that they do not have the change. They are distributing tickets since morning. Roadways is service provider and the conductors should learn one thing that is to be polite.
