Is it a lie for the cashier of Dong 'an Liu's Beauty and Health Club to pay 500 yuan deposit?
This is not a lie. Generally, cashiers have to pay a deposit, because cashiers deal with money after all, so they have a sense of responsibility to themselves, and another is to prevent some people from getting dirty, but such people are still rare after all, but people who do cashier work will ask for a deposit, which will be required by all walks of life. If you don't do it, you will retire.
