Before you can start ordering, first login using your RU account.
On the home page, there is an overview of all venues where you can place orders. Is your favourite venue not available to order? Too bad, you can only wait...
Check out the queue of orders and decide whether you want to place an order. Hit the 'place your order' button and pick the products you want to order. After placing your order, you will be added to the queue and your orders will be prepared with love.
Note that you can not order an unlimited amount of products, there are restrictions on how many items you can order in total and of a specific kind of product.
After placing your order, all you can do is wait. In the queue of the venue, you can see how things are going. Orders with a -icon are your own orders.
You may notice that your orders are displaying a Not paid label. If you already paid for your order, but it is not ready yet, this label will become Processing. It is not required to pay upfront, you can also pay when your order is ready.
When your order is finally ready, the label will turn into Done (if you still need to pay) or Done. Make sure to be present in the venue, because this is the time your name will be called and you can pick up your order!
