Corey Braun, the owner of the franchise in Rancho Cucamonga, Calif., said the gathering was a chance for them to prove that they support their community, regardless of their beliefs about marriage.
"I wanted to show that Chick-fil-A doesn't discriminate against anybody," he said. "We serve everyone. We're happy to serve the community and this was an opportunity to have this group come in and show them our hospitality regardless of their beliefs, sexual orientation or whatever."
Eden Anderson, who serves as a board member for an LGBT rights group, said he was in disbelief by Braun's decision to pass out the coupons.
"What I experienced with the community, is when people are open and apologetic and accepting, it's touching to us," he said. "It feels like acceptance and we just want to be accepted and engaged in society, so when it's confirmed, I think the overall reaction was, yes, certainly that Chick-fil-A in Rancho Cucamonga is welcoming to us."
It was just last year that the COO of Chick-fil-A, Dan Cathy, made LGBT groups outraged after he revealed his stance against gay marriage. Many called for a boycott of the restaurant chain.
Supporters of Cathy held a "Chick-fil-A Appreciation Day," with hundreds showing up at the Rancho Cucamonga restaurant to show support.
Braun said Cathy's comments were taken out of context and do not reflect the outlook of the chain.
"Chick-fil-A has never been about hate," he said.
