In customer service, an important aspect of communication is:

Being clear and approachable is essential in customer service communication because it fosters an environment where customers feel comfortable expressing their needs and concerns. Clear communication ensures that the customer understands the information being provided, which can minimize confusion and lead to a more satisfying interaction. An approachable demeanor encourages customers to engage, ask questions, and seek clarification if needed. This approach helps build trust and rapport, which are critical components of effective customer service.

In contrast, using technical jargon can alienate customers who may not be familiar with specific terminology; thus, it can hinder effective communication. Speaking only when necessary might come across as disinterest or unavailability, failing to engage customers adequately. Highlighting sales data may be relevant in certain contexts, but it doesn't prioritize the immediate needs or concerns of the customer, which should be the primary focus in customer service interactions.
