Her Facebook post went viral, and she's still searching for the "mystery man."

Nicole Singh posted on her Facebook page that her dad, who is a disabled veteran, was going to pay for his groceries at a Safeway in Sunnyside, Oregon the other day when he realized that he was without his debit card He called her, asking if she could drive his card over.

She never got to do it - somebody paid his $60 bill for him.

I'm just so dumbfounded and awed by this man's generosity!! Needless to say, there are truly angels among us, and we have every intention of paying it forward. I just hope I can meet this amazing mystery man one day and thank him for how he treated my father.

See? There ARE good people in the world...and they always pop up exactly when you need them.
