If you want to open a snack bar, you must first understand snacks and know how to make snacks. This is the most basic. Then opening a shop includes a series of work such as site selection, decoration, material selection and operation. You can open a shop directly if you have experience. If not, you need to study systematically and create employment guidance. It is not difficult to learn snacks. Generally, you can master many categories in a month or so. Going to the snack bar involves a lot of service work, and there is little opportunity to learn the core technology in time. If you want to learn snacks on a zero basis, you'd better choose a regular school and make a comprehensive comparison, including tuition, courses and teaching quality. There are many snack bars now, so the future of this area is still very good.
