The breakfast shop is opened, and you can eat it for three days for free. What's the harm and what's the benefit? Older people who have had experience in this field will give you advice.

There are many shortcomings. Merchants want to earn popularity by losing money, but losing money does not necessarily earn popularity. During the three-day free period, safety, order and supply are all big problems. After three days, those greedy customers will not come again. Breakfast is a small business profit, so there is no need to engage in activities such as three days free. You can engage in low-price promotions such as free rice porridge for the first three days, or 20% discount for the first three days, buy two and get one free.
