Chick-Fil-A restaurants nationwide Friday were packed with patrons dressed like cows. The 10th annual Cow Appreciation Day had customers dressing as bovine to receive free food from the popular food chain.

Guests that showed up dressed "head to hoof" in cow apparel received a full combo for free. Those that were partially dressed in cow attire still got an entree item.

Chick-Fil-A is expecting to serve over one million customers nationwide on Cow Appreciation Day.
