Dinner doner

Having just finished my dinner doner, I am standing in Adleshof, waiting for the tram back to the Bergers' apartment in Karlshorst, when I am approched by a shaggy man.

Man (something like): Eisen wien iesen schtraben?
Me: I'm sorry, I don't speak German.
Man: Oh. My mistake-- I must be in the wrong country.
