Prepare sandwiches for the customers. Pay attention to the drawing in the order, because not all customers want all fillings, for example a common order is a sandwich with just ham and eggs.
With the mouse, drag the ingredients to do the sandwich, then drag the sandwich to the client. Both the ham and the egg require to be cooked before being put in the sandwich. You have to put first the bread, then the ingredients that fill it, then the bread cap and then you deliver the sandwich.
