Courier station owner Liu Guifang, complaining that two packages were too few, mocked a father and daughter sending mail to their faces. Relying on years of cooperation with a major client, she long ignored service rectifications. Until the client found a new choice, her 600 orders plummeted. She lowered prices, posted videos, and reported competitors, but the more she fussed, the more passive she became. In the end, her nine-year-old shop closed down. Only then did she realize that what ruined her business wasn't those two packages, but the respect and diligence she had long since lost.
