The idea of ID pictures was great, the women see it and don't care, until now nobody get the pictures to avoid more women step on it. They even step on purpose, like this woman in blue high heels, she was looking to the pictures and did nothing to avoid step on it. Another girl stomped so hard with her heel that leave the perfect sole print on it, you can see it in close up. It's in total 4 pictures I used, one was kicked away and I put a new one in its place.
