A commis de salle is the junior assistant to the chef de rang in the dining room brigade, helping to organise and run a station of tables. Duties include laying up, carrying dishes, serving bread and water, clearing plates, and supporting the senior waiter during service. The role teaches the choreography of the dining room: timing, tablecraft, guest awareness, and teamwork under pressure. Like the kitchen commis, it is the entry rank where standards are learned by doing. Attentive commis de salle make the difference between smooth service and chaos, anticipating needs before guests notice them.
