Tamil Nadu State Transport Corporation [TNSTC] — Rural buses not operating on time

I have travelled from Tirunelveli to Sriviliputhur recently. While I return the bus I took at Sriviliputhur around 12:30. It was running very slow and stopped at all stops. Atleast this is acceptable as there are passengers from rural villages. But the driver stopped at rajapalayam for lunch and took break as 30mins. Almost 45 passengers in the bus was sitting at hot sun. Before dropping for lunch conductor didn't even inform the time for break. And later again they stopped for 15 mins at sankarankoil. Totally unfair. When a passenger asked conductor about such delay he started arguing and said that the government instruction is like that. I really appreciate for such a good higher official for maintaining such a discipline in their organisation.
