Because Su Wanqing received cold treatment at Zhou's Restaurant for asking for an extra half bowl of rice, she promoted the company to add a "Lin's Small Kitchen" trial run, without forcibly canceling the original designated location, allowing employees to choose voluntarily. Lin's won a good reputation through open kitchens and visible cooking, free rice refills, and noting dietary restrictions. After Zhou's business declined, false information and improper competition appeared, and Su Wanqing publicly clarified using complaint records, process materials, and employee rosters. The company improved systems for public bidding, traceability disclosure, employee evaluation, and decentralized auditing, making Lin's a benchmark designated location.
