Merchants can't force consumption. Setting the "minimum consumption amount" itself is an unfounded behavior. It is illegal to ask consumers to pay. Consumers only need to pay the actual amount of goods purchased, and requests exceeding the actual amount can be rejected.
If merchants take other compulsory measures to demand payment, consumers can complain about their rights through consumer associations.
