An old man in plain clothes walks into a high-end sales office, only to be blocked and looked down upon by salespeople for his ordinary attire. Only intern salesperson Lin Xiao looks past appearances, takes the initiative to greet him, patiently explains property details, and truthfully outlines the actual conditions of the facilities. Facing an unreasonable bet publicly made by colleagues and mockery from the crowd, Lin Xiao does not back down and upholds professional ethics. Unbeknownst to everyone, this visitor treated as an ordinary old man turns out to be the father of the group's senior executive. He decides on multiple properties on the spot, successfully closing a large subscription, which subsequently exposes the store's internal tampering with sales performance attribution.
