In Rock Hill, S.C., Wednesday, customers were waiting 75 minutes for a Chick-fil-A chicken sandwich, when they could have driven down the road to McDonald’s and been in and out and five minutes. It surely seemed strange to at least a few observers, but the folks in Rock Hill — and at jam-packed Chick-fil-A restaurants across the country — were making a statement, standing up for a chain that has been criticized by media members, politicians and activist groups because of Chick-fil-A President Dan Cathy’s support for the biblical definition of marriage.
