What should I do if Bai Piao leaks the meal code of the Meituan takeaway cabinet?

You can call the police. Because Meituan take-out is a commercial platform, not a charity, customers can report to the police if they intentionally harm the interests of businesses by Bai Piao, which constitutes an illegal act. Bai Piao will have a bad influence on other consumers, damage the reputation of businesses, and then affect the turnover and profits of businesses. We should resolutely crack down on and punish Bai Piao's behavior and safeguard the legitimate rights and interests of merchants and other consumers.
