A_customer is the most important visitor on our premise. A_customer is not dependent on us. We are dependent on A_customer. A_customer is not an interruption on our work. A_customer is the purpose of it. A_customer is not an outsider to our business; A_customer is part of it. We are not doing A_customer a favor by serving A_customer. A_customer is doing us a favor by giving us an opportunity to do so.
