When I was in my teens, I got my first "real" job. It was working at a service station.

The station was a part of a chain of dozens. The owner was a well-known local multimillionaire. For whatever reason, he happened to be at my station on my first day at work.

He and I spent over an hour pumping gas, checking oil, doing an oil change, patching tires, and so forth.

I learned a lot more than simply how to work at a service station that day. I continued working at that station for over a year. Never saw the guy again. As I recall, when I started he had stores over half-a-dozen states.
