To be successful in your interactions with customers whose values, beliefs and experiences differ from your own, you will need to broaden your scope of knowledge related to interpersonal; communication, especially nonverbal signals (cues).
Because nonverbal communication styles and interpretations often differ from person-to-person and from one culture to another, the likelihood of breakdowns in interpretation and misunderstandings of nonverbal cues is high.
To enhance your awareness and skills in this area, attend seminars on nonverbal communication and cultural diversity, explore books, articles and other information online or at the library, watch other people and talk about differences with others that you know. The more you know, the better your interpersonal communication skills will likely become.
