To open a restaurant and do business, we should first establish the belief that customers are God! That customer, you should discuss it with him and tell him that you don't want this kind of accident. A bug doesn't mean that the hygiene quality in your is poor. Now that it's summer and it's a restaurant, these things are inevitable! Just like when you buy an apple and there are bugs in it, do you have to go to the vendor who bought the apple for compensation? You should reason with him. But if he belongs to that kind of trouble-making type, he is not satisfied with whatever you do, then you will admit that you are unlucky! But I think it's all right, this is life, experience more things and don't regret this life! At the same time, I wish you a prosperous business!
