Customers are not an interruption of our work. They are the purpose of it. Customers do us a favor in doing business with us. We aren't doing customers a favor by waiting on them. Customers are part of our business - not outsiders.
Customers are human beings with feelings, and they deserve to be treated with respect.
Customers are people who come to us with needs and wants. It is our job to fill them. Customers deserve the most courteous attention we can give them. Customers are the lifeblood of this and every business. Customers pay our salary.
