The user generates a new order id while on FoodPanda from the "Generate" tab. Then shares the new order id with his or her buddies.
Buddies add the id and input their name in the Join tab. The extension will then redirect them to the restaurant chosen by the user that generated the order.
When food selection is complete on FoodPanda, the users must press "Send checkout items to Order".
The user that generated the order can then press "Update Master Basket" and see the updated cart.
The extension keeps the order items for every participating user.
When the order is complete, you can delete the order summary by pressing "Close Order!"
