The individually wrapped Kraft American Cheese was the worst for the cashiers "I'm sorry, you need to get this from the deli"Ughhh, I loathed WIC day. I worked the dairy, and I can't tell you how many times I got asked which chocolate milk was WIC approved. I used to tell them "The white kind". Even worse for cereal, it said right on the voucher the only brands eligible (Kix, Shredded Wheat, Cheerios, etc), and people still tried to get Froot Loops or Cocoa Krispies.
