I booked the ticket at last moment, apparently i got the last row seat (which is not the semi sleeper seat). somehow i managed to travel from erode to bangalore, in bangalore when i saw few seats in middle row are available. so requested the conductor the avail me that seat. he said "sir please be seated we will arrange a seat for you". then the conductor started to fill the bus with passengers. when i again asked him for the seat he refused me by saying that the bus is fully filled now, and started arguing with me. The only good thing about the journey is bus reached pune on time.
