Delhi Transport Corporation [DTC] — Misbehaviour of ticket checker

I was traveling from Kashmiri Gate to kapashera border (orange bus). I just entered in bus and was standing near conductor giving him 2 rs to buy my ticket. It was large crowd near conductor who buying ticket. Two ticket checker had entered and asked had i taken my ticket and snatched my 20 rs from my hand and asked me to get out fron bus. I asked them I was buying ticket. But they didn't listened anything and asked me to shut my mouth. I was fined 200rs and I had paid. But behaviour was really bad and disrespectful. If I was in queue to buy ticket not travelling without ticket. Delhi Transits need to check this type of employees.
