The Paperboy
About 200 people lived in Milton, North Dakota. I delivered the Grand Forks Herald (大福克市先驱报) to just about all of them. It was my first job, and I was ten. I didn’t just throw the paper onto people’s front lawns. Because everyone knew me and my family, I was careful not to make mistakes. If I did, I knew I would hear about it. So I knocked on doors, said hello and asked people how they were. Then I handed them their paper. Contact with customers, and good service, are what separate winners from losers. I believe that managers cannot serve customers effectively without meeting them. You’ve got to get out there. Not only do I visit supermarkets around the world but I receive and distribute a weekly report listing customer complaints (and compliments). Nothing is more important in business than listening to your customers. As my employees know, I am passionate about customer service. That passion was instilled in me back in Milton, N. D., delivering papers after school.
