Not a dang thing wrong with bagging groceries, in fact its a much classier and noble job than a pollster.
Three lessons I learned in the ‘80s working there after baseball was over for me for the summer:
1) It was fun, the clerks and other employees loved my grandfather, and I was happy to work there for free. It was "community organizing" as a capitalist would see it.
2) My grandfather was my hero to me. He owned his own store! I thought he was the richest guy in the world. Little did I know he was, but it wasn't in terms of collecting money.
3) He ran his own “charity” at the store. Can't afford to pay your grocery tab this month? No matter. It's more apt to be forgotten or traded for services once you get back on your feet.
I learned so much from my grandfather's grocery store. I still draw on it today.
