Notice that if $x$ is negative, then the whole thing would amount to a negative number. Also notice that if $x$ is positive, then $|x-|x|\text{-}|$ would be $0$, hence the whole thing would amount to $0$. Therefore, $\frac{|x-|x|\text{-}|}{x}$ is positive $\boxed{\text{for no non-zero real numbers }x}$.
