the biggest fear is to reduce profits to attract customers. Nowadays, the catering market is flooded with many people every year, and everyone invests in it to open stores. If they can't make their own features, they have to reduce profits to snatch users from other businesses. As a result, profits are getting thinner and thinner, costs are getting higher and higher, and stores are also facing collapse. Unless there are some good catering modes like "one case, one product", which can not only control the quality of each takeaway, but also greatly reduce the cost, it will have greater competitiveness in the market.
