It's always like this at first. I can't remember. Just greet customers according to the cashier's seven-step order. If you can't remember your meal, you can go back once in a while. It's good to be accurate at first, but you should be able to master it yourself after four days. If you are unfamiliar or uncertain, you can ask your sister or manager next to you. Don't be shy about asking questions. When you are free, you can familiarize yourself and write down some. Some of them can learn to make some if you can watch them. For example, there are scraps of paper on the ground, and when you see it, sweep it. Don't let other partners remind you that you are sweeping the floor. If you don't know where it is, just ask. It will be fine after a long time.
