And sho vie tell me?

At the retail space at Privoz plate:
Watermelon 1 - 13 hryvnia
3 Watermelon - 40 hryvnia
 - Give me a watermelon.
Pays 13 hryvnia, takes watermelon. And so it is repeated twice more.
 - I bought you three watermelon for 39 hryvnia, although it says here that you sell them for 40. What are you stupid!
 - And so all the time ... Take three watermelon and taught me how to trade!
