Which of the following is NOT a component of good customer service?

A fundamental aspect of good customer service is to foster an open and engaging communication environment. This involves asking open-ended questions that invite customers to share their thoughts and needs, rather than limiting them to a simple "yes" or "no" response. When representatives use closed-ended questions, it can hinder the flow of conversation and leave important details unaddressed, potentially leading to misunderstandings or a failure to fully meet customer needs.

In contrast, the other choices relate directly to positive customer interactions. Attendance at store trainings ensures that staff is well-equipped with product knowledge and service techniques. A positive attitude is crucial for creating a welcoming environment where customers feel valued and appreciated. Quickly acknowledging customers shows attentiveness and respect for their time, crucial elements of building a strong customer relationship. These components all contribute to an effective customer service strategy, while the use of closed-ended questions can detract from that goal.
