When I was a kid, I remember going to a small hobby store to buy a couple of bottles of paint. The bottles were $0.25 each, and I had exactly $0.50. I took my bottles to the register and was told the total was $0.51, because of sales tax. So I only purchased one bottle, and the total was $0.25. As I was leaving I realized that the tax had been wiped out, so I went back in and purchased the second bottle for $0.25 too. These days it's common to find pennies on the ground because they aren't worth the effort to bend over to pick them up. I pick them up anyway, because I still remember a time when they mattered.
