Don't worry, the cashier is not an accountant and doesn't need so many theories. Cashiers in supermarkets are simpler than those in hotels. (Cashiers in big hotels need a month to get familiar with the system. If the waiter doesn't order with the ordering system, you need to be very familiar with the coding of the food. , so the speed can't get up for two days a day)

(1) As long as you can operate the pos machine (that is, the machine for customers to swipe their cards, which is not complicated and can be learned in a few minutes).

(2) How to operate the cash register (this is also very simple, just need an old cashier with work experience to teach you)

(3) Some simple statements will vary according to the different requirements of each supermarket, but it is also very simple.

Conclusion: Believe in your own strength and don't be afraid of anything. For a cashier, it is important that you are bold and cautious. It is enough for you to remember this one. If you collect money, it is better to "sing tickets"-the so-called "sing tickets". Because some people will mistakenly think that you are given 100 instead of 50 and so on. -I'll be glad if it helps you. I have trained cashiers and worked as a guest cashier. Anyway, don't be too nervous. When you are busy, be especially wary of those little people who disturb your thinking.

By the way, I once lost more than 90 yuan, and I am not afraid of losing face on Baidu.

Specifically, when I was busy, he handed me 100 (he bought a small thing worth a few dollars), and then after you gave him the change, he suddenly said, I have the change, you can give it back to me, then give it to you, and then you can give it back to him-

If it helps you, please adopt it:)
