Protestors gathered outside the Omaha Chick-fil-A at 34th and Farnam on Friday, holding up signs discouraging people from eating at the restaurant.
The flap began last month when Chick-fil-A president Dan Cathy told a religious publication that the company backed "the biblical definition of a family."
"Kiss In" protests by same-sex couples were planned Friday at Chick-fil-A locations nationwide.
Hundreds of thousands of customers showed their support for the restaurant Wednesday during an "Appreciation Day.” Chick-fil-A says it set a one-day sales record.
Meanwhile, police are investigating graffiti at a Chick-fil-A in Torrance, California. The graffiti on an outside wall of the restaurant said "Tastes like hate" and had a picture of a cow.
