Irene opened a coffee shop in town and she has to manage all things every day. she bought machines for this: one of them is used to fill the glasses with purple drink, the other allows to put the sauce on sandwiches and the last adds chocolate one ice. orders are advancing on a treadmill. irene will have to manage each dish and go to the right machine to finish it. you will move to irene so she gets to do everything on time. if a customer is happy, he will pay you and will come back to order something else. never forget that!
