Depending on which hall/block you are in, you won't necessarily even have a cupboard to yourself, especially if you are in Hawthorns A-M blocks, for instance. Most people keep what they can in their room, which also means it doesn't go missing. Some of the kitchens do have room for people to fill a plastic box/tub with things and keep it in the corner of the kitchen, but it does depend on exactly which block you end up in.
