What tool is essential to place in the Bird sink?

The towel is essential to place in the bird sink because it serves multiple important functions in maintaining cleanliness and hygiene. It is typically used to thoroughly dry off items that have just been washed, which helps to prevent water spots and ensures that surfaces are properly sanitized.

In a kitchen setting, especially in a fast-food or food service environment like Raising Cane's, it is crucial to have absorbent materials that can be used to wipe down surfaces and clean up any spills quickly. The towel also provides a safe and gentle surface for handling delicate items, preventing breakage or damage. The absorbent nature of towels makes them particularly effective in this role, ensuring that the items you handle come out clean and dry, ready for use.

The other options may also have cleaning functionalities, but a towel stands out for its overall versatility and effectiveness in food service operations, making it indispensable for the bird sink.
