Every business needs to have some kind of customer service. Customers need to know that they are going to be served when they need it. They also want to be sure that are their questions are going to be answered on time. Customers like when they are being paid attention to. They also like if the customer service is friendly. Nobody likes to be treated badly. The minute your customers walk through the door of your business, you need to greet them. You can do it personally or you can hire a sales person to do it for you. Customers need to feel special and you need to find a way to make it possible.
