Sales individuals in the tire industry can use the nonverbal cues of their customers to help develop their relationship, create trust and ultimately increase sales. Failure to maintain eye contact with a sales person may be a sign that the whole truth may not have been told by the customer. The customer may be embarrassed or may feel they are hiding something and therefore unable to maintain eye contact. Eye behavior and body language may also indicate distrust for the service personnel. Moving away from a paper work order to explain necessary repairs toward a show-and-tell approach where prospects can engage with displays, models, and pictures may help relax the client and develop trust.
