Do supermarket cashiers need health certificates?

It's normal to start work slowly (practice makes perfect). The key is (confidence) that it is difficult to succeed without it. You must be careful when handling tickets in special jobs. Never remember to collect money to find out if you overcharged others. Don't lose your temper with others. Learn more about yourself. Pay less for yourself. If you receive the loss of counterfeit money, count it before going to work. Be clear after work. In a word, you should balance your income and expenses.
