Generally speaking, among ten groups of customers, at least one will raise不满意 places about 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 a small business, can't make much money, but everyone is not easy, let's be friends." This response delays a bit and wins some favor. It's worth exchanging three yuan for a returning customer. It's better not to take the initiative to give customers less money. 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, you can win their 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 customers, understand the shortcomings in your barbecue skills, and build a little rapport with the customers. For example 3: When a customer says your barbecue tastes bad. First, you need to admit the mistake, apologize to the customer first, then taste it immediately to see where the problem lies. For small orders, waive the bill; for large orders, offer a discount.
