Ellen Degeneres caught someone stealing at her show and it got super awkward quickly

When you are told that you can take one free item, is it stealing to take more than one? Ellen Degeneres put out a table with some goodies from her show, The Ellen Show, with a sign that read “Please pick 1 item to commemorate your visit, only 1 per person please”. Obviously Ellen rigged the area with hidden cameras to capture what her audience would do. One lady decided to take more than one item and Ellen called her out on the show. Do you think Ellen was right to do so?
