People who started eating at CFA due to their moral stance will, if they haven't already, go back to their normal routines, if it didn't include CFA. Sales aren't down at all..........they've actually been up in many places, especially during Chick-fil-A appreciation day created by anti-gay Republican, Mike Huckabee. Millions have been making a point to eat there. But the damage to the brand will eventually show itself. It's going to be a long-term process.
My guess is that it was yesterday's news and the public have already moved on.
