Signs do not mean free.
There are numerous signs these days.
Signs for phones and signs for homes.
Signs for toys and signs with joy theres signs to buy gas and signs that give you gas.
Signs for books and signs for a fish hook.
The sign that people look the most is the sign that doesn't say free.
These days nothing is free there is always a catch.
So the next time look at a sign read it carefully.
It might say free.
