The first moment came when I was in the local dollar store. There was an older woman in front of me just wrapping up her goods.
Before I could even offer to help, the young cashier gave her a big smile. She said, "Oh, don't worry about it," and sent the woman on her way.

I gave him some money and told him he could put it in the cup. As I watched the young man gave my son a big smile and said, "Thank you!" My son told him, "No problem." When my son came back to me he said, "That was good. Now he can get better."
