Go to the supermarket
I went to the supermarket the other day with 10 yuan. I was a bit hungry, so I decided to buy a small pack of cookies which cost me 4 yuan. After I ate them, I was still hungry, so I decided to buy a small bag of potato chips which cost me another 3 yuan. After I ate them both, I was no longer hungry. However, I was very thirsty and wanted to buy a large bottle of milk to drink, but I didn’t have enough money left because even a small box of milk would cost me 2 yuan and I needed 2 yuan to pay the bus fare. So I gave it up at last.
