He tells the shopkeeper the smallest bill he has, and she rounds his amount to the nearest number he can pay. For example, if the smallest bill Mirko has is a hundred bill, and he wants to buy 150 Kunas of candy, the shopkeeper rounds his amount to 200 Kunas. If he wants to buy 149 Kunas of candy, the shopkeeper rounds his amount to 100 Kunas.
