Now, first, what can you deduce from this sign?
ANSWER (highlight to the right of this to see): The floor is frequently slippery.
If you got it right, congratulations on your skills of deduction. I guess if you can’t make that deduction, you deserve to fall on the floor. 
Also, from the graphic, it seems like the sign is actually warning you that the floor frequently contains Portal
PS – This is a joke, not a real test. If you got here by googling…this probably wasn’t what you were looking for.

Elementary. Therefor it was the last thing i deduced.
Others being.
:The person in the picture is right handed. (When gripping something the hand you use most often is the hand that requires the least grip on an object)
:30 something white male.(obvious reasons)
:The picture was taken a while back(judging by the phone model)
:And the picture was taken in a bathroom after use but before washing of hands
(again obvious, When going to use the bathroom your almost in too much of a rush to
notice a signs play on deduction and when using an electronic device,
people normally don’t want it wet & either towels are behind you,
in which you wouldn’t have noticed the sign or in front of you
in which the sign sparks your interest 1st.)
Thanks for your time if you read this and for the 35 sec. it took to deduce it all.

It says :
“Please Watch your step
Floor is frequently wet
Floor is slippery when wet”
from there it states that floor is “FREQUENTLY” wet
and the FLOOR is SLIPPERY WHEN WET
therefore the having that the floor is “FREQUENTLY” wet
it also means that the floor is “FREQUENTLY” SLIPPERY . . . .
as simple as that,.???? ^ _ ^,
