Which of the following is an example of non-verbal communication in a customer interaction?

In customer interactions, non-verbal communication encompasses all forms of communication that do not involve spoken or written words. Appearance plays a significant role in this type of communication, as it can convey a variety of messages about professionalism, trustworthiness, and attention to detail. For example, how a customer service representative dresses, their grooming, and overall presentation can influence a customer's perception and feelings about the service they are receiving.

When someone presents themselves well and is appropriately dressed for the context, it can create a positive impression that contributes to effective communication and customer satisfaction. Similarly, body language, facial expressions, and eye contact also fall under the umbrella of non-verbal communication, but appearance is a clear and immediate way that customers assess interactions.

In contrast, the other options do not directly represent non-verbal communication. Resolution refers to the outcome of addressing a customer's concern, course conditions relate to specific features or situations relevant to services provided, and perception typically involves the interpretation of information rather than a non-verbal signal itself. Thus, appearance is distinctly linked to non-verbal cues in customer interactions.
