Bring a pen and paper. Remember what you want to recite. Just go home and carry it. When I first went, I had no choice. You can only learn more about the keyboard by yourself. They will teach you. Seven steps:

1 Welcome customers (within 5 seconds)

2 o'clock food (in-class or takeaway)

3 suggestive sales

4 repeat order content

5 packaging products

6 Change and repeat the meal again

7 present catering and thank customers.
