Updated 10/08/2026 5 min read

I squinted and saw through his intentions: This chain restaurant was just an experiment. Once my shop is reorganized and business resumes, he will immediately lead a crowd of people to repeat the previous trap. On the day of the festival, I went to the chain restaurant first, turned on the recording device, and stood in the corner observing the entire process. Lam Than still plays his old tricks, each table is full of expensive dishes. When paying, he accumulated a series of flawed coupons. The total cost was more than eight thousand yuan, and in the end, I only paid 0.08 yuan. The restaurant owner saw the payment record and collapsed on the spot, dragging Lam Than to demand the difference. Lam Than's attitude was arrogant, insisting that the coupon was valid and that neither the platform nor the police could prosecute him. His classmates who didn't know the truth still tried to help him, criticizing the store owner for being petty and not being able to take advantage of the incentives. Amidst the chaotic scene, I walked up directly, took out my phone, played the previously recorded audio, and presented the coupon scanning notes and screenshots of evidence of the platform vulnerability. The recording clearly echoed throughout the restaurant. In the conversation between Lam Than and his friend, words like "scanning the error card to harm the seller", "last time Giang Du's restaurant almost went bankrupt, unfortunately he reported that the store was sealed so he ran away", "wait for his store to reopen, call more people to directly collapse the store" were clearly transmitted to everyone's ears. The entire lobby immediately fell silent. The classmates who had previously helped Lam Than criticize the restaurant owner were all stunned, the persecution and trust on their faces gradually receded, leaving only fear and disgust. After listening to the recording, the restaurant owner immediately reported it to the police and submitted all the evidence I provided to the platform's customer service department. Lam Than's face turned pale, he rushed forward in panic and wanted to steal my phone. I leaned over and gently avoided it. "Jiang Yu, when did you secretly record? You intentionally designed to harm me!" His voice was sharp, angry to the point of losing control. "Harm? From beginning to end, the one who intentionally plotted against others, took advantage of system vulnerabilities to maliciously damage the interests of the seller was you." I calmly took out the complete chain of evidence. "You took advantage of the platform's code flaws to scan a series of high-value unconditional deduction slips. Illegally, maliciously consuming at four restaurants before and after, causing hundreds of thousands of accumulated economic losses, there were signs of fraud. Recordings, screenshots, account cash flows were all iron evidence." There were waves of criticism in the crowd: "It turns out Lam Than was not generous at all in inviting guests, but relied on loopholes to trick the shop owner into paying!" "Last time I went to Giang Du's restaurant, luckily it was sealed in time. store, otherwise his family would have really been harmed to the point of bankruptcy." "Before, it was said that his family was rich and generous, but it turned out that he relied entirely on illegal tricks to pretend to look good, so disgusting." "Continually harming stores like this, this is no longer taking profit, it is illegal, right?" Each look of rejection and criticism fell on Lam Than, everyone instinctively backed away, not wanting to have anything to do with him anymore. The crowd that was surrounding him just now was flattering him, but at this moment they all avoided him as if they were avoiding evil. Lam Than stood alone in the middle of the hall, the dazzling appearance of the male god of the past no longer remained. His hands were clenched, his eyes were red, he couldn't say a single word of excuse. Not long after, the police received a report and arrived at the restaurant. I proactively stepped up, handed over all recordings, screenshots, account cash flow and evidence of platform vulnerabilities that had been classified and arranged.

I fully narrate the entire process of Lam Than repeatedly taking advantage of illegal coupons to maliciously consume, defrauding the seller of services and causing great economic loss. The police in turn compared the evidence, confirmed that the accumulated amount of money involved exceeded fifty thousand, meeting the criteria for establishing a fraud conviction. On the spot, they summoned Lam Than to the police station to receive an investigation according to the law. When Lam Than was taken away by the police, he turned his head and stared at me, his eyes filled with resentment, but he no longer had the strength to threaten me. During the subsequent interrogation, the complete chain of evidence was presented right in front of him, and Lam Than could not deny it. He honestly admitted that after discovering the platform vulnerability, he registered multiple accounts to scan a series of large-value deduction slips. Because he wanted to take revenge on me, he maliciously harmed restaurants many times and confessed the entire truth of his crime. The amount of money involved is large, many crimes have been committed, the circumstances are serious, the prosecutor's office prosecuted according to the law. On the day of the trial, I, as an important witness, went to court and submitted all backup evidence. The court combined the amount of money involved, the number of times the crime was committed and the situation of many sellers suffering losses to make a verdict: Lam Than committed fraud, was sentenced to a term of imprisonment and a large fine.
