Share your kindness story

I was at the grocery store trying to figure out how to use WIC for the first time and I was having some trouble getting the exact correct items. I felt so embarrassed and like I was inconveniencing the person behind me. I offered to let the person go first, but he kept telling me that he wanted to wait behind me. He left the line and a few minutes later a store manager gave me a gift card for $100 and said that the man that had been behind me in line purchased it for me. I have such gratitude for the selflessness and kindness of the stranger I met at the grocery store. I never saw him again and was never able to thank him, but I will always remember him and if I am ever in a similar situation, I will definately pay the kindness forward.
