This is not the LTCM strategy of using leverage to suck up pennies but literally! I was at the line in McDonalds one day and saw a cleaner sweeping up pennies into his trash receptacle. If I had seen the pennies first, I probably would have pounced on them. After all, the kids in school were participating in Greg Mortenson's Pennies for Peace campaign.
It is strange to think that our society is so wealthy now that even a cleaner will not pick up pennies for himself. Certainly, a panhandler would even refuse pennies these days - it's not "brother can you spare a dime" these days but "brother can you spare a dollar".
