Don't think about pink elephants

My boxing classes take place on the gallery above a pool run by the city. We all use the same change rooms.

Recently, two signs were posted in the change room. The first one prohibits the possession of any device capable of taking pictures, including cell phones.

You can imagine how well people comply with that one.

The second sign prohibits taking pictures in the change room. Despite the fact that it's much more reasonable, every time I see it, I want to take a picture of it.
