It starts with how you talk with them. And you don’t need to memorize any special words or magic sentences. The rule is simple: when talking to a customer, be sure to make the conversation all about them. Let them talk about their needs, what they hope to get out of buying your product or service. If they want to complain, listen. They want to be heard more than anything. Since you’re trying to make them feel like they’re the only customer you have, act like it. When dealing with that one customer, no one or nothing else matters at that moment.
