Xiao Taimei, owner of Taimei Restaurant, abandoned her original business intentions due to investment losses. She skimped on meal portions, sold spoiled food, and presold meal cards to cash in, ultimately losing the five-year group meal order with Shunda Logistics. The roadside stall Tang sisters adhered to integrity, providing full portions and proactively refunding price differences, winning diners' praise and being invited by Shunda Logistics boss Lin Chen to move into the company cafeteria. Xiao Taimei's malicious report against competitors failed, and she finally closed her shop and refunded meal cards, paying the price for her untrustworthiness.
