Bus traveled mostly on inner broken roads (Tirunelveli, Kovilpatti, Madurai and some unknown places) rather than NHs.
Driver is more old sentimental staff (should not ask destination time to him as he is driver and responsible for all). I could not get my tentative destination time from staff even ask only by my mouth. Because of that, i could not book a taxi in tambaram from my phone. I also wanted to know whether it is coming through Tambaram or direct Koyambedu through bypass. I get reply only "Ellam avan Seyal (God only decides)".
