Emmm, in this precise case, it is - if you don't put your -1 in a else
statement, without the return, you'll always get -1...

Now, I'd probably write it like this :

   def get_server_index(server)
     if self.servers.include?(server)
       self.servers.index(server)
     else
       -1
     end
   end
