I gave up on that the other day. After waiting in a long line for ten minutes without it moving, I decided to check out my own groceries. I only had about ten items anyway. I rang things through. I pulled out my purse and started feeding cash into the machine. Suddenly I realized that I had a balance of $1.45. I don't have a credit card any more. I didn't have my checkbook with me, I think it has a $5. balance. I looked around to see if there was a familiar face to borrow from. No luck. Just people waiting in line, waiting for me to move on.
I began digging through the bottom of my purse. I kept coming up with pennies. I would plug them in as fast as I found them. The balance slowly moved to $1.05. Then I found a quarter and two nickels! It really doesn't matter, there is still a balance.

I would have been glad to put something back, have it taken off my bill. But there were no store workers in sight. So I kept digging through my purse. I didn't look up at the people behind me. I was too embarrassed. After more pennies, a few dimes another nickel my balance was down to thirty cents. I remembered that there was change in a tray in my car. I tried to imagine how I could go out and get it--still no store workers in site. I started taking everything out of my purse and shaking it. I could feel the impatience of the people in line behind me. The weight shifting, the sighs. My predicament had to be obvious. No one came to my rescue.
Finally, a miracle! Two quarters tumbled out of my Kleenex packet. I quickly fed them in. Now I even had change coming back. I quickly gathered my things and dashed out the door without looking behind me.
I have seen people in similar predicaments, and I've always stepped forward to help. Just placing a quarter down and walking away so as not to embarrass them. From this day forward, I will watch more carefully to seek out anyone in such a situation. Because the little things like that can make such a difference in the long run.
