80 Rupees for 30 minutes sleep

Woke up. Went to the kitchen only to find out that the stove is gone. That stove is someone else's. The raw matetials i bought for is just a waste now. The stove was supposed to be returned to its owner by yesterday. It did not happen. So I used it to cook lemon rice for lunch yesterday. I hoped the same would happen today and bought flour for dosa. But it did not. If I had gotten up 30 minutes earlier, I would have prepared something, saving me 80 bucks at the least. Is 30 minutes worth 80 rupees?
