Then, the operator wants the clothes to be neat.

The kitchen should be clean, and people nowadays are very afraid of getting hepatitis.

The waiter should also look clean and don't wipe it with a black rag.

Store size is not important.

Also, people who are in direct contact with food should not touch money. Even if there is, bring a clip or something. It's the same as collecting money.

It is best that all the operations can be seen by diners.

For example, the restaurants near me are all transparent kitchens.

I think restaurants that look reassuring will do well.
