Who approves requests to deviate from the standard 90 minute serving period permanently?

The correct choice is the garrison commander, as this individual is responsible for overseeing operations at the installation level, including food service programs. The garrison commander has the authority to make significant decisions regarding policy and operational procedures, which includes approving deviations from established serving periods. This responsibility ensures that any changes to the standard procedures are aligned with overall command objectives and maintain the integrity of the food service program.

The other roles mentioned, such as the food program manager, regional commander, and dining facility supervisor, have different levels of authority and responsibilities. The food program manager focuses on the operational implementation of the food service program, while the regional commander manages multiple installations and oversees regional operations. The dining facility supervisor directly manages the day-to-day operations of a specific dining facility but does not have the authority to approve permanent changes to standard operating procedures like the serving period. Each role plays a vital part in the food service program, but only the garrison commander has the final say in approving permanent deviations.
