Tea has always been a popular beverage, but the latest trend in China is to create a new type of tea-drinker - one who becomes a "foot slave." This development comes from the company T, which has created an AI-powered system that analyzes customers' behavior and uses it to turn them into foot slaves. The system starts by identifying individuals who are likely to become foot slaves, based on their drinking habits and other criteria. It then offers them rewards for completing certain tasks, such as cleaning the floors or massaging feet. Over time, these tasks become more demanding, until the customer is fully indoctrinated and becomes a loyal servant of the company.
