Chapter 4 — Coupon Trap

I calmed my voice and reassured: "We can still take out the fines and rectification money for the time being. It won't cause the family to go bankrupt. Once the rectification is complete, we can re-open the shop after the inspection." Father was silent for a long time, letting out a long sigh, feeling tired, but also understanding that every word I said was the truth. Completing that order would be irreversible. I conveniently suggested: "It's a good thing that the store is going out of business around this time. Dad has worked hard in managing the restaurant for so many years, and has never had a proper rest. I'll book a ticket for him to go to the nearby mountain and river scenic area, go out for fun for half a month. Leave all the arrangements in the store up to me. When dad comes home, everything will be handled properly." Dad was already not at ease about the store, so he spent many more days of hard work and today he was in constant fear, physically and mentally. They were all tired, hesitated for a moment then nodded in agreement. That night I finished booking the homestay in the scenic area and the bus ticket, and the next morning I took my father to the bus station. I told him over and over to just relax and go out, not to worry about anything in the shop. After sending my father away, I carefully stored my valuables at the cashier counter, locked the door, and returned to school. The other two roommates were not in the dormitory because they were going to school, leaving only Lam Than sitting alone in front of the desk. Seeing me push the door back, he immediately put down the phone, stood up and walked in front of me, turned around and closed the dorm room door, blocking out the outside sounds. In the cramped dorm room, Lam Than tore off his usual gentle masculine disguise, his eyes filled with gloom and cruelty, and lowered his voice to warn: "Giang Du, consider yourself lucky, relying on reporting your shop to avoid a life. But don't be complacent, this time is just the beginning, next time I won't let you have another chance to escape." I raised my eyes and lightly glanced at him, without half a trace of emotion. I walked straight around him to my desk, opened my textbook, completely ignoring his threat. Lam Than saw that I didn't pay attention, his anger rose even higher, he stepped forward to block my sight: "Did you hear that? In my hand there are many large value discount coupons of the same type. I want to take people to your restaurant to spend money at any time. You can't always rely on the restaurant seal to protect yourself, right?" My fingertips gently stroked the page of the book, without raising my head, I replied lightly: "It's up to you." My coldness made me speechless, my chest heaving violently. He glared at me for a long time. Seeing that I still didn't pay attention, he could only angrily return to his seat. Occasionally he would glance at me with resentful eyes, secretly plotting a new round of plans. I understand clearly in my heart that Lam Than will absolutely not let go. He hated me for stopping him from drinking and making noise late at night, and was angry because today I ruined his plan to destroy the restaurant. He will definitely take advantage of the platform's coupon loophole to take revenge on me again. I can't just rely on temporarily sealing the shop for passive defense. I must collect all the evidence in advance. Completely cutting off the way for him to take advantage of loopholes to extort money from sellers, causing him to suffer legal consequences. The next few days, I silently paid attention to Lam Than's every move the entire time. I bought a tiny recording pen online and carried it with me. As long as Lam Than mentions coupons, defrauding the seller, and related content, I record them all to save. I logged into the online ordering platform, flipped through all the coupon rules, took a screenshot and saved the coupon's issuance channel and usage limits.

0.01 yuan deducted 2,000 yuan. I asked my high school friend who works in information technology to look up the record of receiving this type of large-value discount coupons in the management system, and clearly investigate the entire process of Lam Than taking advantage of illegal loopholes to hoard thousands of coupons. In just one short week, I had gathered a complete set of evidence: In the recording, Lam Than and his friends directly said that they had solved the vulnerability in the platform system, could scan unlimited large-value unconditional deductions, and used the same trick to harm three restaurants. Each time it costs from tens of thousands to more than ten thousand, the actual payment is less than ten yuan, the seller has no way to claim rights, can only admit bad luck. Screenshots prove that this type of large-value deduction voucher has no official distribution channel, but Lam Than took advantage of code flaws to maliciously scan them in bulk. Voucher receipt records in the platform system clearly show that many accounts under the name Lam Than have accumulated and illegally scanned thousands of high-value deduction vouchers. I backed up all the evidence to the cloud and USB twice, quietly waiting for Lam Than to take the initiative. As expected, there were three more days left before the restaurant's renovation deadline expired. Lam Than posted a message in the group's large group, saying that he wanted to make up for the regret of not being able to have a banquet last time, and booked a popular chain restaurant to hold the party.
