[Resolved]  TNSTC — Indecent behaviour of crew

My son, who is a first year college student, was travelling from Walajapet to Kancheepuram by Tamilnadu State Transport Corporation bus (Route No.156; TN 23 N 1789) on 08 Feb. 2010. He boarded the bus at Walajapet, but took a five minutes time to ask for a ticket (Ticket No.027832 with RT No 501). Though he asked for the ticket, he himself voluntarily, the conductor abused him vulgarly and shouted at him using bad language for the delay. Though he expressed sorry and requested him not to use bad language, he continued it for some time. During the travel when he asked some details from the driver, he also joined the abuse.
Who gave them the right to use bad language and abuse badly for the mistake he did inadvertently? Is this the way for the public servants to behave like this to the younger generation? This kind of attitude and approach by the crew towards the growing young generation is totally wrong in my opinion and it is also much harmful to the society indirectly in general.
My son was offended by this very much and wanted to know the way to express his anger towards their behavior. May I request the authorities concerned to take note and do the needful to provide facilities to express their grievances to ventilate and also to train their crew appropriately to deal with the passenger.
