I taped a one dollar bill to the back of a smile card and placed the card near the selection buttons of the company vending machine. After an hour I revisited to see if someone had or was partaking my gift. Nope, it was still there. After lunch several hours later both the card and the buck were removed. I just hope the individual will "pay it forward." I explained to my team mates what I was doing and they are ready, willing and able to join in on the "kind train." I'll distribute some of my Smile Cards to them.
