A customer is the most important person on our premises.
He is not dependent on us.
We are dependent on him.
He is not an interruption to our work.
He is the purpose of it.
He is not an outsider in our business.
He is part of us.
We are not doing him a favour by serving him.
He is doing us a favour by giving us the opportunity to do so.
