When I lived in Charleston SC, my hobby, believe it or not, was picking up roadside trash. I'd walk around with a pick-up tool and plastic bag; it's amazing what people will throw out of cars! One day I took a shortcut through the parking lot of a doctor's office, and found a new $20 bill right next to the handicapped parking space at the front door. I took it in to the office, gave it to the receptionist and explained what had happened. When I left the office, I found another one. I checked the parking lot and sidewalk and found a total of $240 dollars, all in crisp new twenties. I gave them all to the doctor's receptionist and nurse (made sure there were at least TWO people in that office who knew the story, figured it was less likely that someone would keep the money!) Later that week I called the office, just out of curiosity, to ask if anyone had ever claimed it. The receptionist said that one of their patients had, that she had just been to the bank before she came to the doctor's office, and had gotten her rent money in cash. Never knew whether or not that story was true, but I felt better for not having kept the money. I like to think that it was true; if not, it's on someone else's conscience, not mine.
