Pranksters from the Chick-Fil-A Foundation have exchanged a fake coupon for a meal on the condition that they renounced their homosexuality.
The stunt, posted on YouTube, finds two men handing over a coupon to a slightly confused server at Chick-Fil-A that promises anyone who gives up their homosexuality a free chicken sandwich.
The company, which is the second largest chicken fast food firm in the US, has donated millions of dollars to anti-gay groups including the Family Research Council, Exodus International and Focus on the Family.
In 2011, Mr Cathy rebutted accusations of being anti-gay, saying he and the company had “no agenda against anyone”.
But last year, he affirmed that Chick-Fil-A is opposed to equal marriage.
He said: “We are very much supportive of the family – the biblical definition of the family unit. We are a family-owned business, a family-led business, and we are married to our first wives. We give God thanks for that.
“We operate as a family business … our restaurants are typically led by families; some are single. We want to do anything we possibly can to strengthen families. We are very much committed to that.”
