What customer service principles should supervisors instill in their team?

The emphasis on timeliness, accuracy, and friendliness as key customer service principles underscores the foundation of effective customer interactions. Timeliness reflects the importance of responding promptly to customers, which contributes to a positive shopping experience and demonstrates that their time is valued. Accuracy ensures that the information provided and services rendered meet customer expectations, fostering reliability and trust.

Friendliness is essential in building rapport with customers, creating an inviting atmosphere where they feel comfortable and appreciated. These elements collectively enhance customer satisfaction and loyalty, which are critical to Costco's mission of providing high-quality service.

Other options reflect valid qualities but do not align as closely with core customer service principles crucial for a successful retail environment. For instance, creativity and innovation might play roles in strategy and product development but are less immediate in day-to-day customer service interactions compared to the straightforward expectations of timely and friendly service.
