The importance of bread as a daily staple meant that bakers played a crucial role in any medieval community. Bread consumption was high in most of Western Europe by the 14th century. Estimates of bread consumption from different regions are fairly similar: around of bread per person per day. Among the first town guilds to be organized were the bakers, and laws and regulations were passed to keep bread prices stable. The English "Assize of Bread and Ale" of 1266 listed extensive tables where the size, weight, and price of a loaf of bread were regulated in relation to grain prices. The baker's profit margin stipulated in the tables was later increased through successful lobbying from the London Baker's Company by adding the cost of everything from firewood and salt to the baker's wife, house, and dog. Since bread was such a central part of the medieval diet, swindling by those who were trusted with supplying the precious commodity to the community was considered a serious offense. Bakers who were caught tampering with weights or adulterating dough with less expensive ingredients could receive severe penalties. This gave rise to the "baker's dozen": a baker would give 13 for the price of 12, to be certain of not being known as a cheat.
