How to distinguish two-way mirrors from ordinary mirrors

When we visit toilets, bathrooms, hotel rooms, changing rooms, etc. How many of you know for sure that the seemingly ordinary mirror hanging on the wall is a real mirror, or actually a 2-waymirror (i.e. they can see you, but you can't see them).  So try this simple test to distinguish two-way mirrors from ordinary mirrors:
Place the tip of your fingernail against the reflective surface and if there is a gap between your fingernail and the image of the nail, then BE CAREFUL, for it is a 2-way mirror.
However, if your fingernail directly touches the image of your nail, then it is a genuine mirror.
