My mom came back from the market and said:

I bought some big, three pieces. Pretend with the seller whether they get 2 in the backpack or not. I tell her, give two in the backpack and one in the hand, well, or if, on the contrary, one in the hand and two in the backpack... And both minutes hanged for five. We hear that something is wrong here, and what is wrong, we cannot understand...
