"I didn’t mind making the cake, but I also felt his purpose in ordering the cake was he wanted to troll us and to say we were being discriminatory to him. That’s exactly what he wanted," she said. "I know there have been cases where LGBTQ have sued bakeries for not making wedding cakes and all the courts say if you provide a service, you can’t discriminate. We make cakes. I can’t discriminate and say I won’t make the cake, but I can choose not to write homophobic comments."
