Popeyes mocks Chick-fil-A's National Sandwich Day blunder

The rivalry between fried chicken sandwich giants Chick-fil-A and Popeyes reached a new level this week, when Chick-fil-A forgot what day it was and Popeyes was quick to take a dig.

Chick-fil-A sent out an email to its subscribers earlier this week to promote National Sandwich Day on November 3. The only problem: November 3 falls on a Sunday -- a day when all Chick-fil-A locations across the United States are closed.
