The miller had to be able to negotiate with the evil spirits. Not only was the "knowing" miller paid more, but so was the reliable miller, the one who, according to the peasants, knew his business and was honest with people in terms of maintaining the order and payment.
According to the beliefs, the miller's power was lost if he cheated the peasants or broke the custom of serving them in turn. According to popular beliefs, breaking these traditional obligations could bring the miller's work-related evil spirits down upon him, causing interference in the grinding process, damage to machinery, and even the miller's own drowning.
One of the restrictions imposed on the miller was the prohibition against shaking off flour. Failure to follow this rule could result in the miller contracting a fever and experiencing "a lifetime of shaking."
