Linda is the manager of a small beauty salon. She deals with different kinds of customers and has to ensure that the customer needs are identified and satisfied. To develop an effective customer service, what should she do? Always use "they" language when dealing with customers and refer to "company policy" when handling customer problems. Continually strive to gain new knowledge and skills and deliver the level of service equal to that offered by established salons. Focus on taking a one-time service or sales opportunity approach instead of developing an ongoing relationship with customers. Exclude the information collected from customer feedback surveys when measuring the service performance of her salon
