This incident happened to me onboard Bhopal New Delhi Shatabdi. I was traveling from Bhopal to Mathura on this train. They started serving dinner after Agra and I knew I wouldn't be able to finish my dinner before the train arrives at Mathura. Then the pantry guy offered to pack the dinner for me. You will be amazed what all he had packed. Parathas,2 dal,2 paneer,2 dahi,rice salad etc. I was shocked when I opened the package at my hotel in Mathura. As there was so much food I gave some to the room boys there. All this because I had tipped a 100 at Bhopal itself.
