restaurants know their profits and losses, so you can count your costs, and there is sales. You can get it by comparing a few boxes.

if you have the cost, you have the cost of renting a house, and then maybe this is your own house, so it will not count. Then there are labor costs, materials costs, utilities and so on. There are also some consumption such as chopsticks, disposable chopsticks or napkins. This is also the cost. It is also possible that it is a loss fee.

Well, then you make a profit, that is, you sell it. Well, catering, whether it's take-out or in-house food, has to be calculated.

You see, if you say, er, the cost is high, then you will lose money. If people say that you make more profits, then you will win with a profit.
