So I had such a situation. I buy a cupcake from my grandmother in the market. Money only 5000. I give a bill. He says: No surrender, I will come, I will exchange. She took the money. I stand and wait. 10 minutes. 20 minutes. After half an hour, I realized I was dropped. And on the box there was a gram of 400 cucumbers and a couple of packs of cabbage, rubles for 500. He took what was there and went home. At least it was delicious. But the grandmother of Pidar-si is old.
