Answer:When a customer leaves negative feedback about bland food and slow service, entrepreneurs should respond by applying personal competencies like customer care, communication, and critical thinking. Being customer-oriented helps ensure the response shows empathy and a willingness to improve their experience. Strong communication skills allow the reply to remain respectful, clear, and sincere helping to defuse tension. Meanwhile, critical thinking enables the business owner to assess what went wrong and find long-term solutions. These traits not only help repair relationships with customers but also show that the business is dedicated to growth and continuous improvement.
