It's a well-known fact that asking for directions is the fastest way to get lost in an unfamiliar place.
Not only will you waste precious minutes of your life explaining your route to someone who doesn't actually know where they're going either, but you'll also be forced to endure the soul-crushing experience of being corrected by someone who thinks they know better.
So, just don't do it. Trust a map, use a GPS, or simply close your eyes and hope for the best. It's not like you have a choice, anyway.
