Food runners are an important part of a restaurant staff and serve as assistants to the waitstaff. Their main duties are to deliver, or "run" food to tables once a food order has been prepared by the cooks.
Food runners also assist other restaurant staff members with duties such as clearing and cleaning tables, filling water glasses and refilling drinks, maintaining cleanliness in the kitchen and customer areas and returning plates to the kitchen.
Food runners must be efficient, detail-oriented, courteous, pay attention to cleanliness and have team player attitude. A positive attitude and a courteous demeanor with customers is a must, as well as making sure you are clean and presentable.
