My parents ran a small restaurant. The restaurant was open 24 hours a day, seven days a week.[22]And my first job when I was six years old was shining shoes for customers. My duties increased as I grew older. By age ten I was clearing tables and washing plates.[23]My father made it clear that I had to meet certain standards. I had to be on time, hard-working and polite to the customers. I was never paid for any work I did.[24]One day I made the mistake of telling Dad I thought he should give me 10 pounds a week.

This taught me quite a lot.
