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