What will Officer Trainees not do while carrying trays?

The correct answer is B, "Square corners." Officer Trainees are specifically instructed not to square corners while carrying trays as a part of maintaining proper decorum and ensuring safety in the dining area. Squaring corners involves turning sharply at an angle, which can lead to spilling food or drinks from the trays they are carrying, potentially creating a mess or causing injury.

In contrast, running, speaking, and stumbling may be behaviors that could take place but are discouraged for various reasons related to maintaining order and discipline. Running can lead to accidents, and speaking, while generally discouraged during specific formal settings, is not outright prohibited. Stumbling indicates a loss of control but usually relates to a broader emphasis on maintaining one’s composure and balance while performing tasks like carrying trays. Overall, the emphasis on not squaring corners is crucial for fostering a disciplined dining environment and ensuring that trainees maintain professionalism.
