Why would you anonymously tip your garbage man through a QR code? Meet him out there at butt-crack AM on your garbage day and look him in the eye and give him the cookies or the pie or whatever, and tell him he's a hero. If you're lazy give him cash but do it in person. Give him a reason to treat you well. QR code keeps you relatively anonymous and ruins the connection and any chance of humanity-upside for you.
