Not to scare you, but to make sure that you aware.
Many of the hotels and textile showrooms cheat the
customers this way & watch privately.
HOW TO DETECT A 2-WAY MIRROR
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, r actually a 2-way mirror i.e., they can
see you, but you can’t see them). There have been many
cases of people installing 2-way mirrors in female
changing rooms or bathroom or bedrooms. It is very
difficult to positively identify the surface by just
looking at it. So, how
do we determine with any amount of certainty what
type of mirror we are looking at?
CONDUCT THIS SIMPLE TEST:
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 it is a
GENUINE mirror. However, if your fingernail DIRECTLY
TOUCHES the image of your nail, then BEWARE, IT IS A
2-WAY MIRROR! (there is someone seeing you from the
other side). So remember, every time you see a
mirror,do the “fingernail test.” It doesn’t cost you
anything. It is simple to do. This is a really good
thing to do. The reason there is a gap on a real
mirror, is because the silver is on the back of the
mirror UNDER the glass. Whereas with a two-way
mirror,the silver is on the Surface. Keep it in mind!
Make sure and check every time you enter in hotel
rooms.May be someone is making a film on you.
