Final answer:
For guests on a wait at a campus restaurant, the most practical option is providing a pager or taking their contact information so they can be alerted when a table is ready. This allows guests, especially busy college students, to use their time more efficiently while waiting.
Step-by-step explanation:
When guests are on a wait at a campus restaurant or similar establishment, there are several options available to enhance their experience. Although seating them immediately would be ideal (A), it may not be possible if there are no available seats. Offering a complimentary meal (B) is a generous gesture but may not be feasible or standard practice. Taking their orders while they wait (C) could improve service efficiency, but might not always be practical. The most common and viable option is providing a pager or taking their contact information (D), so guests can be notified when their table is ready.
Given the scenario of busy college students trying to find seating in a campus restaurant during a limited break between classes, it's clear that timing is crucial. These students are concerned with the time and the opportunity to eat as a group. Leveraging a system that offers them to leave their contact information can be an effective way to handle the wait, allowing them to maximize their break time without the constant worry of checking for table availability.
