Resident students who do not want to participate in a meal during the week (Monday to Friday), must sign out by 9 a.m. on the day of the meal. 
Resident students wishing to have meals during the weekend must sign in by 6:30 p.m. the day before the meal.
Students living outside the school may register for school meals but must sign in by 9 a.m. Those wishing to have meals at the school on the weekend are to sign up for the meals by 6:30 p.m. on Friday evening. 
Those who have not signed up may still opt to participate in a meal (subject to immediate payment of the regular price for the meal, and subject to availability of food for the particular meal, as determined by the responsible member of the kitchen staff) and may then immediately sign up for any remaining meals for the weekend. 
Furthermore, to prevent waste, students should only sign up for meals that they actually intend to partake in. If known in advance that a student will miss a meal because of church activities, another student is allowed to prepare a plate, put the student‘s name on it and set it aside.
