"Chick-fil-A Appreciation Day," an event Wednesday in which supporters converged on the fast-food establishment to back its  chief executive's controversial stance on gay marriage, is not the end of the controversy.

Gay rights supporters are planning a "National Same-Sex Kiss Day at Chick-fil-A" on Friday. As part of the event, couples are encouraged to go one of the chicken restaurant's locations and take a photo or video of themselves kissing.

"Let's show Chick-fil-A thanks for their support of Love, Equality, and the Real Definition of Marriage! Invite your friends!" organizers said on its Facebook page.

Gay rights advocates on Wednesday also suggested that supporters eat at KFC instead of Chick-fil-A.

On Wednesday, much of the attention was focused on supporters of the embattled eatery.
