Dear Supermarket Visiting Idiots,
DON'T PULL YOUR HAND AWAY FROM ME JUST BECAUSE YOU DON'T WANT THAT TINY PIECE OF PAPER, OR I'M GOING TO DROP ALL YOUR CHANGE ON THE DAMNED FLOOR AND WATCH AS YOU PICK IT UP YOURSELF!!!
There are bins on the way out for your convenience. The fact that you don't see them is none of our concern.
Thank you for your attention.
