Kindness at fast-food restaurant

It was summer and I had gotten one of the few jobs a 14-year-old can find—working at Burger King，a fast－food restaurant．It  16  wasn’t a good job，but it meant money，  17  was something I needed.

One day，I was working behind the front counter，taking  18  .The customers were coming and going，and the woman who  19  didn’t seem any different from most others.

She ordered her meal and I told her the total.As she searched  20  her purse to find some change，the woman soon  21  that she was about a dollar short.“I’m  22  to say this,but I guess I won’t be able to make my purchase  23 ，”she said sadly

That’s when I had the idea of paying the difference for her. She refused at first，but after I 24  ,she agreed.She thanked me and moved to the end of the counter to  25  her order.I continued with my work and thought  26  more of it

About an hour later  27  had slowed down and I was waiting for my next customer.Then I glanced over towards the  28  and saw the same woman whom I’d helped with the money entering again．I  29  recognized her.

She walked straight up to me and said，“I want to thank you again for what you did.You see，I’m a diabetic(糖尿病患者),and  30  I need to eat something right away．That’s  31  I came in earlier．If you hadn’t helped me as you did，I  32  have fainted.Thank you．”

She handed me two dollars,  33   I’d given her.

34  the woman walk away,I realized that God had used me to help me.In the end,I was  35  not only with money but also with the satisfaction of knowing that I’d helped someone out of a tight spot.
