Bethelites got the menu in advance. They would take leftovers after the meals and put them in the fridge in their room. They would then eat in their room (married couples especially) heating up things. No every food people like was offered at bethel or something you hated like liver, then they might buy some food (liitle canteen to buy from at Bethel). Many rooms now have stoves, and before toaster ovens, convection ovens, etc.
Is the WTS providing food for breakfast, lunch, (dinner) is what I would ask. Bethelites have been cooking in their rooms for some time.
