What is the proper procedure for responding to a guest at the switch?

The correct choice emphasizes the importance of ensuring that you are fully attentive when greeting the guest. Waiting for a brief moment, such as one second, allows you to be prepared and focused on the guest's needs, enhancing the interaction quality. This slight pause demonstrates professionalism and readiness to engage, which is important in establishing rapport and ensuring effective communication.

In hospitality and service environments, first impressions are crucial. By waiting just a moment to compose yourself and ensure you’re not distracted, you create a positive experience for the guest right from the start. This approach prioritizes the guest's experience without appearing rushed or inattentive.

The other methods, such as responding immediately or waiting a longer time, can either overwhelm the guest with a hasty response or suggest a lack of urgency or professionalism when they are held on the line. Seeking to finish another call before addressing the new guest can also create a negative impression, implying that their call is less important.
