Gay rights activists and other supporters of marriage equality plan a national “Kiss In” at Chick-fil-A restaurants Friday to protest the fast-food chain owners’ opposition to same-sex unions, two days after gay marriage foes delivered the chain a one-day sales record.

Hundreds of thousands of customers, many of them conservative Christians, attended “Chick-fil-A Appreciation Day” at more than 1,600 locations on Wednesday, following a call from former Arkansas Gov. Mike Huckabee, a Baptist minister and Fox News talk-show host.

Chick-fil-A vice president Steve Robinson said the company won’t release sales figures for Wednesday. Customers lined up outside restaurants and the Rev. Billy Graham, the 93-year-old evangelist, dined on a Chick-fil-A lunch on the record-setting day.

“We are very grateful and humbled by the incredible turnout of loyal Chick-fil-A customers on August 1 at Chick-fil-A restaurants around the country,” Robinson in the statement.
