Chick-fil-A restaurants became hotbeds of cultural tension yesterday when hundreds of thousands turned up at fast-food joints after the chain placed itself at the center of a row over gay marriage. Drive-through lanes were backed up and dining rooms packed as some diners showed support for the chain which was lambasted when the CEO said he opposes gay marriage. More than 640,000 people pledged to attend Chick-fil-A Appreciation Day – an event organized by former Republican presidential candidate Mike Huckabee to support ‘a company run by Christian principles’. Gay rights supporters also turned up outside the restaurants with rainbow-colored posters, bearing slogans such as ‘HateFul-A’.  They have promised a counter-rally at Chick-fil-A, organizing a ‘National Same Sex Kiss Day’ at restaurants across the country.
