What non-verbal sign might indicate customer satisfaction during a conversation?

When assessing customer satisfaction during a conversation, one non-verbal sign to look for is pupil dilation. This physiological response can indicate a variety of emotional states, including interest, excitement, or pleasure, all of which are associated with positive feelings and customer satisfaction. When a customer’s pupils dilate, it often suggests that they are engaged and receptive to the conversation, which is an encouraging sign that they are satisfied with the interaction.

In contrast, the other options typically represent negative feelings or disengagement. For example, frowning usually indicates confusion, displeasure, or frustration. Looking at one's watch may suggest impatience or a lack of interest. Crossing arms is often perceived as a defensive or closed-off posture, which can signify discomfort or a barrier in communication. Thus, pupil dilation stands out as a positive cue in the context of customer satisfaction.
