Tamil Nadu State Transport Corporation [TNSTC] — I'm complaining about travel experience

I travelled at Kanchipuram to arcot bypass. Generally I'm not interest to travel in private bus. So I already waited for an hour to travel in government bus with available of seat. Finally I got Kanchipuram to vellore bus (TN 29 N 2949) and also got seat. But in between the travel, the conductor said, don't sit arcot passangers, only sit vellore passangers. How can they telling this. Kanchipuram to arcot also travel time of an hour. And the bus fare of rs 47. Is he right in saying that even if I pay 47 rupees and travel for an hour, I should not sit on the seat? I feeling very bad about it.
