Being Asked For Direction to Places of Kufr, Shirk or Immorality

What should we do if we are walking in the street and someone comes up to us and asks us the directions to a place of Shirk such as a Hindu Mandir/Shia Mosque or to a place of immorality like a nightclub (and you have a feeling that if they go to those places they are going to indulge in shirk or immorality)? Should we give them the directions or do something else? What is a good alternative to giving them the directions?
