Having a positive attitude and a friendly, helpful tone can make a big difference when you are trying to sell a product to a customer. A customer does not want to deal with an employee who acts negative and like they do not want to be at their place of business. If the company’s own employees do not want to be there, why would the customer want to come back and purchase more from them? Treat them like their business is important to you and that you would like them to come back again. After they leave a business, custoemrs remember how employees treated them. If they were friendly and helping them with whatever the customer was looking for, the customer would return again to the business in the future. If they were rude or ignored the customer, then they would not come back again.
