A button will be under each person's cart if they have items. If you are logged in as a user with items in the cart, you will have a button under your personal cart to confirm the order (this can also be unconfirmed). On clicking the confirm button, a request is sent to the server to update the status. If the server accepts it, the page is refreshed to ensure that if the order is completed by this, the cart page is cleared. For all other people, buttons are shown which are not interactable, displaying the status (confirmed, awaiting confirmation)
