Strangers in the grocery store

My sister came up to visit me on Sunday. She needed to borrow a dress for her class reunion. She texted me early Sunday morning and said 'If you can, hold off on breakfast. I'll stop at the store and pick something up.'

She arrived around 9 am with fresh fruit and coffee cake. No juice. She said "Let me tell you what happened.

I was in the self-check line at Kroger. I went to scan my items and reached in my purse to get my money ready. And surprise, no wallet! I started to put my stuff back when the man behind me asked what the problem was so I told him. He said 'Will $20 help' and handed me a $20."

She got his business card and planned on sending him a $20 later that day. He said not to worry about it but she was still going to mail it. He certainly didn't have to pay for our breakfast. But what a nice thing to do!!??
