hello friend, in your case, you should have pre-job training, or an old employee (the so-called master) to take you (of course, it also depends on the scale and configuration of the catering enterprise). You should learn more in the early stage, remember the service process first and be familiar with it! Then remember the knowledge of dishes, and be familiar with the simple production process and the characteristics of single products (main and auxiliary materials, taste, nutritional value,,,) will help you to promote sales smoothly! If you are majoring in this major, do a good job in interpersonal relationship first and work slowly!
