My father had done it when he was young, so he taught me 37  to do it well, telling me to 38  to shine the shoes again if the customer wasn’t 39 .
I was proud of working in the restaurant   40 I was also working for the good of the family. But my father   41  said that I had to meet certain standards(标准) to be part of the team. I   42  to be on time, hard-working, and polite to the 43 . I was    44  paid for the work I did at the restaurant. One day I made the mistake of suggesting to Dad that he 45   give me $10 a week.

It has nothing to do with 55  that team is for a family restaurant or the US Army.
