题型:填空题

Yesterday I went to our local grocery store. I often go to their deli counter, and I understand that it can get a little confused for the workers. So normally none of them ever take the time to smile or seem overly friendly. But yesterday it was completely different. I was pleasantly surprised to be greeted with a very welcoming smile by the young man behind the counter. He never sighed heavily or slumped back and forth like he didn’t want to be there. He was all by himself and quite a long line. But not once did he act concerned about it. He just did his job efficiently and acted very kind the entire time.

I was so impressed that I approached the manager. I explained to her that I often visit the deli counter and I have never been greeted with such kindness. She agreed with me that he was a wonderful person and she thanked me for sharing my feelings with her.

As I was walking away,I could hear her approaching the young man with,“I just got a wonderful compliment(praise) about you.” I couldn't hear everything she was saying,but I knew that she did thank him. I couldn't help but smile!

Later I had to pass by the deli counter to get onions. There was no one there,except the diligent young man. He didn't say anything,he just smiled at me. I realized that I hadn't done a huge deed that day,but that small deed made a small difference to someone.I love seeing people smile. I just received my smile cards and I wish I had one with me that day. Maybe I will drop one off at the deli a different day! It's amazing how good I felt after that.

So,friends,the next time you are in a grocery store,retail store,restaurant,or anywhere that someone is working hard,letting them know in some way can mean so much. I hope you get a smile out of it like I did!
