The term 'cafeteria holder' can be summarized as a person who is responsible for carrying trays of food in a cafeteria. This job requires the holder to transport the trays from the kitchen to the dining area, and then collect them after the meal is finished. The TRAY is an essential tool for this job, as it allows the holder to carry multiple plates of food at once. The holder must also ensure that the trays are clean and free of debris before and after each use.
