I have been stopping at Sonic off and on since November. Most days my receipt is affixed to the side of my drink with an advertisement sticker. I routinely pull it off, crumple it up and throw it away. Recently I realized a small strip of paper containing words of encouragement was also attached. I have begun each day to look forward to that little strip of paper and to be disappointed on the days I don't receive one.
The first time I read one I was amazed.
Have a great day!
