Usually burgers are made on special equipment. And to distribute them to customers, they use a special conveyor or involve waiters. Our chef just tosses the burger. Somehow he manages to make a product that does not crumble during the flight. Earnings depend on how whole the filling remains by the end of the flight and how far the burger flies. Once you have accumulated a certain amount, you will have the opportunity to improve your product or equipment. Make the most of your opportunities and be successful. Good luck!
