 set of points at which $f$ is quasi-finite is an open $U \subset X$.
 Let $Z = X \setminus U$. Then $s \not \in f(Z)$. Since $f$ is proper
 the set $f(Z) \subset S$ is closed. Choose any open neighbourhood
-$V \subset S$ of $s$ with $Z \cap V = \emptyset$. Then
+$V \subset S$ of $s$ with $f(Z) \cap V = \emptyset$. Then
 $f^{-1}(V) \to V$ is locally quasi-finite and proper.
 Hence it is quasi-finite
