The cooperative bought six plant-protection drones, and director Qian Guoqiang wanted to cut Luo Chuan team's service fees in half, while still making them responsible if problems occurred. Luo Chuan refused to sign the contract, and old clients were also attracted by low prices, turning to the cooperative one after another. However, new equipment paired with a one-size-fits-all operation plan caused abnormalities to appear successively in multiple farmland plots, and rework, refunds, and compensation followed one another. Luo Chuan, who was once disliked for being expensive, won back trust by inspecting plots one by one and making precise remedies. When Qian Guoqiang offered a higher price to invite him back, he proposed to deal with the farmers' losses first. Machines can replace people in doing work, but cannot replace professionalism, let alone responsibility.
