Generally, among ten groups of customers, at least one will raise不满意的地方 with your barbecue skills. For example 1: A customer spends 83 yuan and says it's fine to pay 80 yuan when checking out. How should you respond? "We are small business owners and don't make much money, but everyone is not easy, so let's be friends." This response delays a bit and gives the customer a favor. It's very cost-effective to exchange three yuan for a returning customer. It's better not to actively give less money to customers. Nowadays, people don't care about those few yuan. If you mention it first, some customers may become unhappy. However, if the customer brings it up first, then you can give them a favor. For example 2: When a customer spends more than 200 yuan, at this point the gross profit is around 100 yuan. If you're not busy, you can go over and have a drink or offer some cigarettes, communicate with the guests, understand the shortcomings of your barbecue skills, and build a little rapport with the customers. For example 3: When a customer says your barbecue tastes bad, first admit your mistake, apologize to the customer, and then taste it immediately to see where the problem lies. For small orders, waive the bill; for large orders, offer a discount.
