What does the term "behind" indicate in the restaurant context?

In a restaurant setting, the term "behind" is typically used to inform others that you are approaching from behind them, often to avoid collisions in busy areas such as the kitchen or dining room. This communication is crucial for safety and efficiency, helping staff move around each other seamlessly during busy shifts. By alerting teammates to your presence, it allows for a smoother workflow and prevents accidents, ensuring that everyone can perform their roles effectively. This context is vital in a fast-paced environment like a restaurant where spatial awareness is important.
