The Trainwreck star later took to Twitter to clarify her position on having photos with fans.
"Thanks for the kind words and support," she wrote.
"I know there are bigger problems in the world. But this was not right. I'll still take pictures with nice people when I choose to if it's a good time for that. But I don't owe you anything. So don't take (photos) if I say no."
