Customer service is treating your client as if they were the only client you have. Tending to all of their needs and wants. To ensure that your client has the best customer service you must treat them as royalty. There is nothing as refreshing and professional as giving special attention to your client. If a client knows that you care about their needs and their well being. They will care to refer you to others. I once heard that, no one cares what you know until they know that you care.
