When I lived in Russia, Yank tourists would often stop me outside the underground station on Nevskij Prospect to ask for directions to the Hermitage. Nevskij Prospekt is a 4 km long road, at which the Hermitage lies on one end. The underground station where I was approached is about 800m from the Hermitage. At least three times I gave directions emphasising that the museum is at the VERY END of the road, then pointing to the opposite end of Nevskij Prospect. Off they went, happily.
I have an evil streak in me!
