Final answer:
Wait to clear the table until everyone has finished their meal, as it is considerate and proper dining etiquette.
Step-by-step explanation:
Before clearing the table in a dining setting, such as a campus restaurant, it is polite to wait until everyone at the table has finished a course before clearing any plates or utensils. This ensures that no guest feels rushed or uncomfortable while they are still eating. In the scenario described, where students are trying to dine between classes, they may be checking their watches due to time constraints; however, proper etiquette still applies. Caterers or servers should observe and wait until all guests have completed their meal before clearing, especially in situations resembling a college dining hall where people may be on tight schedules yet expect courteous service.
