After Su Xiaowan collected the money, she counted it, finding the amount correct. She demanded the food ration coupons from the couple, reasoning that she had paid with ration coupons when buying her ingredients. She cheekily pointed out that she was saving them the trouble of queuing and wasting their time.
Thus, having parted with 9 yuan, the couple quieted down. The woman probably felt slightly embarrassed about the fuss she had made, especially since it ended up costing them quite a bit of money.
On the other hand, Su Xiaowan was pleased. The cost of the pastry ingredients wasn't much. Four pastries used just over a pound of flour, a little oil, and sugar, adding up to a mere 20 cents. For the 36 pastries, the total cost was 1.8 yuan. With a return of 9 yuan, her pure profit was 7.2 yuan. She was secretly overjoyed by her unexpected windfall.
Her two cousins were stunned. When had their little cousin become so astute? She had set up a perfect trap. Was this really okay?
