Food Bank client handing out worthless bills

I volunteer at a food bank and today was the day for our regular clients to come pick up their Thanksgiving boxes (approximately 20-25 lbs of canned goods, instant potatoes and a gift card from a local grocery store for a turkey or whatever). Families with up to 4 members received 1 box, 5 - 8 members received 2 boxes. And this was in addition to their regular monthly visit. I had a 2 hour shift and we were busy handing out boxes the whole time. Everybody was excited to be there and thanked us for our help.

Well...all except this one guy. He put his 2 boxes in his car and then came back to the door with what looked like a big wad of new bills in his hand. I didn't get a real close look at them, but could make out that the face of the President looked a lot like President Obama. He offered some to us saying that they would be worth as much as real bills in the very near future under this president. All 3 of us volunteers were shocked when he said this and each one of us told him no. He just looked at us then and turned away to walk back to his car. I don't know what got into me at that point. Maybe it was reading several posts here where DUers have said enough is enough and they're going to call out people who do things like this. So I opened the door as he was getting into his car and reminded him that the 2 boxes of food he had just received from us were paid in part by government grants. And he had the nerve to yell at me and say that he paid his taxes. Before I could say anything else, he drove away. Which is probably a good thing because I was really pissed, as were the other ladies.
