Many people have been cheated. Have you ever been cheated?

One day, my family went to my aunt's cigarette shop. We stopped talking when we saw two people walk into the tobacco shop without saying a few words. Two boys, one tall and one short, came in one after another. The short boy is carrying a big cardboard box, which looks heavy. The boys walk slowly. When the short man came in, he pointed to a pack of cigarettes, and his sister quickly took it out for him. The short young man opened the cigarette case when he got the cloud smoke, skillfully took out one and put it in his mouth, picked up a lighter and lit it. The tall young man wandered around the shop without saying a word. Then, the short young man took out a hundred-dollar bill from his pocket and handed it over. My sister looked at it and said I wanted to change a dollar, which was hard to find. The young man took it out of his pocket for a long time, but he didn't find any more money.

He said he didn't have any money with him, so he had to go to the bank to withdraw money, and conveniently put the carton that had just entered the door on the counter. Pointing at the paper box means pressing the paper box in the shop. The tall young man was noncommittal and still stood in the shop, as if he didn't mean to leave. My sister was standing inside the counter, so she had to wink at me and point to the young man who walked out of the door. I understood my sister's meaning and hurried to the door. I followed the short man closely, and after three or two times, I got along with him. I told him there was a bank not far ahead and asked him what bank he was looking for. The young man looked up at me, stopped and returned to the direction of the store. I got up and followed him closely. The young man went back to the store, took out a 50 yuan bill from another pocket and handed it to him, saying that he remembered that there was another bill in his pocket.

When I walked into the tobacco and liquor store, I found that the tall man who had been walking in with him had already left. Sister gave it to him 15 yuan and handed it to the young man. He spit out almost all the cigarettes he had just smoked, fell to the ground, saw that we were all looking at him, picked them up without looking, and walked out casually. When my aunt saw that the young man had gone away, she told us the scam of the two young men. This is an elaborate "chain plan". That short man is the protagonist of the scam. The cardboard box in his hand must be an empty box that looks completely closed. It's a prop, and the tall man is a supporting role. If my sister didn't recognize the fake hundred-dollar bill handed over first, she was directly fooled, and the scam was successful, resulting in a direct loss of one hundred yuan. If my sister doesn't let me follow her and thinks that there is a box of "Wang Lao Ji" in the box, she will cheat me out of a box of cigarettes and pay 35 yuan.

There is also an illusion that people may not want to catch up. Because two boys enter the store together, it gives people the impression that they come together, but once the short boy leaves, the tall boy will definitely leave the store, and he will say that they don't know each other at all. My aunt, who often keeps the shop, fortunately saw through such a cleverly designed "chain plan". I asked, what would you do if we didn't come to the store today, even if we caught the scam? My aunt told me that she would let gay men in the shops around her follow her, and she stayed at the door of the shop. I saw such a scam with my own eyes. Without long-term anti-fraud experience and vigilance, I will definitely be succeeded by such a liar. I don't know. Have you ever heard of a similar scam?
