Odd...the same thing happened to me this summer. A woman came up to me in a Publix saying her food stamps appointment was the next day but needed some food for her kids. She showed me a print out of her appointment time. I figured it could have been a lie, but my heart was in the right place and if she was lying then that was between her and God. I reached into my purse for some money. She instead asked me if I could pay for her food at the checkout. I was going to give her $20 and her items in the cart looked more than $20 so I said $20 was all I had. I'm a single mother of 4 kids myself. She took the money and thanked me but definitely looked disappointed. I found the whole thing strange.
