“A customer is the most important visitor on our premises.  He is not dependant on us.  We are dependent on him.  He is not an interruption in our work.  He is the purpose of it.  He is not an outsider in 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
