learn to read, people

I have a pet peeve about people in our gym locker room. It's very simple. What part of "please do not dress in the shower area" is so hard to understand?

I was especially annoyed today when five people were waiting in line and someone (who had spent a good fifteen minutes inside) walked out of her shower stall dressed in at least three layers of clothing, including an overcoat, nice sweater, and knee high boots. Argh!!
