Pay It Forward - "You Dropped Your Money!"

A couple days ago my partner and I helped a client clean out their basement in preparation of putting the property on the market.  We took a couple of loads of trash to the dump in my partners truck.  On one of the trips to the dump my partner stopped at the bank in town to cash a check and I waited in the truck while he did his errand.  Just after he went in the bank I noticed a woman leaving the bank at a brisk pace, talking on her cell phone with one hand and fishing in her pocket with the other.  I assume she was fishing for the  keys to her fancy car parked a few cars from the truck I sat in.  The wind was a little breezy that day and as soon as she stopped fishing in her pocket a flurry of money fluttered out of her pocket which she was oblivious too.  I shouted out my truck window to her "Mam Mam! You Dropped Your Money!"  She looked over to me, then down to the money fluttering on the ground, never took the cell phone away from her mouth, bent over picked up the money on the ground then got in to her fancy car and sped off while still talking on her cell phone. She never said thanks, she didn't wave nor did she even so much as nod an acknowledgment.  I wonder if she would have done the same as I did for her to someone else who dropped their money?
