I have to start out by saying that what I am about to write goes back to 1962 or so, and I am by far the furthest thing from a racist. Back in '62 I was 9. This was a point in time when Polak was a big word. It was a derogatory word making fun of Polish people. It was said that Polak's were so cheap that they would pick up a penny if you dropped it on the ground. I grew up in Chicagoland, and as you may or may not know, there are more Polish people in Chicago than in any city in Poland or anywhere else in the world. Anyway, we used to throw a penny on the ground and if anybody picked it up we would all yell out, "You Polak. You picked up a penny." We were 9 after all, and this was a funny thing to us, not a racist thing.
That said, a lot of people will still not bend over to pick up a penny if they drop it as if it's too much work to do for a single cent, or maybe they are still stigmatized by the old Polak thing. So there seem to be a lot of pennies on the ground at convenience stores. Two days ago I bent over to pick up a penny and there was a dime and a nickel to boot. That seems to me to be a lot of money to just leave on the ground unless a person is handicapped and can't bend over. If I could pick up 16 cents every time I hit a convenience store parking lot I would go to the store all the time. So I haven't found any silver or other of the cooler coins in the lot, but every penny counts. By the way, we always wondered when we were kids how to spell Polak. There were so many possibilities and we didn't have computers that showed Urban definitions. How did we ever live without computers?
