Hello. Soon I will start working as a cashier in a mini supermarket.

Then answer these questions:

- What is everything fundamental that I must know?

- What is the most difficult thing I face?

- How do you do cash count correctly at the end of each shift?

- Is there any method to make the count fast and not die trying?

Finally, what errors are the most common and how can I solve them? First of all, Thanks.
