Lesson learnt : never travel in a bus with cargo.
For one, they will wake you up when they unload it. Some leave the engine idling. Then they drag you and your already lagging schedule to the oil bunk for a refill. And because of this delay, you might have the grand luck of being in a road block (a result of an idiot of an accident) like I did. There are 50 vehicles behind our bus. Time lost : 4 hours and my serving of poori-masala and hot chai. Goddamit.
