Cow appreciation day is this Friday, which means you can score yourself a free lunch if you get into the holiday spirit. If you go to your local Chick-fil-A location dressed in full cow garb (head to toe), you'll earn a free meal. If you're just looking for a free entree you can go in with a cow accessory. You don't even have to go all out, the restaurant is making it easy for you with a DIY cow costume you can print at home. To claim your free food, head on over your local Chick-fil-A Friday, July 11.
