Among other things I sell U-Haul boxes and packing paper. About 2 weeks ago I goofed and left the front door unlocked when I went to lunch. When I came back there was a $20 and a note on the counter from one of my customers saying that she had grabbed a box of wrapping paper and a couple boxes and to call and let her know if the 20 wasn’t enough for them. I actually owe her about three dollars, Been waiting for her to come back by so I could pay her back.
