(AP) – Gay rights activists are planning demonstrations at Chick-fil-A restaurants to protest the fast-food chain owners’ opposition to same-sex unions.

Meanwhile, police are investigating graffiti at a Chick-fil-A in California. The graffiti discovered Friday on the side of a restaurant in Torrance in Southern California said “Tastes like hate” and had a picture of a cow. No one has been arrested.

“Kiss In” protests are planned Friday, two days after hundreds of thousands of customers showed their support for the restaurant during an “Appreciation Day.” Chick-fil-A says it set a one-day sales record on Wednesday.

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.”
