Serfs had to pay to use the lord’s grain mill and bread oven. They had to pay to use the lord’s carts to carry their produce. The serfs were very angry about that. Many peasants had to pay a fine because they used their own grain mill. The miller charged a fee called (multure), which was usually 1/24 of the total grain milled. The serfs often thought the millers were not honest. Many lords made the serfs use the lord's oven to bake their daily bread.
