Because of the cost, the main reason why drinks in the catering industry are more expensive than those in supermarkets is the cost, not the status symbol. Although the ex-factory price of the same wine is the same, the cost of circulation to various channels is different. The cost of supermarket is wine price+labor+freight+profit+other expenses, taking the route of small profits but quick turnover. The catering industry is weaker than supermarkets in terms of rent, inventory backlog, taxation and profit model. Therefore, if the catering industry wants to make a profit, it needs to reach a certain gross profit of the goods sold in its own stores, otherwise it will be a loss from the perspective of cost conversion.
