What is Customer Service?

"Too often, customer service is viewed as a department, a designated employee's job role, or someone else's responsibility. Because of this limited view of customer service, many employees are content to simply execute a series of mandatory job functions until the end of their shifts—blissfully unaware of the myriad opportunities forfeited to make lasting positive impressions on their customers. To expand on this narrow definition of customer service, I'd like to submit my own definition for consideration: Customer service is a voluntary act that demonstrates a genuine desire to satisfy, if not delight, a customer."
