Welcome to Momma's eating house. The goal is to be the best eating house in the town, and for this we need that your performance to be perfect!
When a customer arrives, click and drag him to one of the tables or to the bar; then click him again to get his order; depending on it, click on the corresponding cooking or expending machine; when the dish is ready, click it and then click the customer to deliver it. When he finishes, click him to get the money and clean the table. You also have to click the trash can to complete the table cleanup. And to avoid impatient customers, it helps to serve them a cup of coffee (click the coffee and then click at the corresponding customer to do it).
