Trick novices into joining those who are willing to take the bait, and it will be difficult to stop after boarding.

The economic account is labor * 2 = 60,000, water, electricity and gas accommodation 1 10,000, rent 50,000, * * *10.2 million, which is equivalent to monthly expenditure10.2 million.

Seven customers are fixed every day every month to deduct the cost of potions just to protect the capital. Calculation: (2000 * 7 =14000-500 * 7 =10500)

If you want to make a profit, you must guarantee 15 customers every day. If two waiters are not exhausted, if more people are invited, the cost will increase, so the cost and profit are the pain points that cannot be balanced.
