India: Samosa yet not selling at cheaper price, why?

 Samosa

Kanpur: Samosa was a snack that had been talked about most during the past many months.

On a pleasant Sunday, there was a paucity of this likeable item of food in famous shops.

While another shop made the customers wait for minutes, as the edible oil was taking time in reaching the boiling point.

The customers were desperate to secure the number of pieces but the shopkeeper was not swift in steaming the samosa. 

Even the shopkeeper indulged in an argument with one customer who was looking young and stylish person. He failed to impress the shopkeeper as he seemed rude to him.

Though the shopkeeper accepted that demand for this stuff has risen owing to a fall in potatoes' prices. However, he was not lowering the price of samosa despite a marked decrease in potatoes price in the retail market.

Consumers raise a query it is neither imported nor refined but prepared in an indigenous way. Even then its price does not go down. Why so?
