Which container is used to transfer ice to the drink machine in the drive-thru area?

The ice bucket is the correct choice for transferring ice to the drink machine in the drive-thru area. Ice buckets are specifically designed for the purpose of holding and moving ice, ensuring that it remains contained and easy to transfer without spilling. They are typically made from materials that are durable and easy to clean, which is important in a food service environment where hygiene is crucial.

Using an ice bucket helps maintain the quality and safety of the ice, as it minimizes outside contamination and ensures that the ice is fresh for customers' drinks. This is especially important in a fast-paced setting like a drive-thru, where efficiency and cleanliness directly affect customer satisfaction.

In contrast, other containers mentioned, like a cooler, may not be as convenient for transferring ice since they are designed for storage rather than quick transport. Plastic containers and metal trays might not provide the same level of accessibility or be as suitable for holding ice specifically. Hence, the ice bucket is the most functional and appropriate choice for this task.
