The old adage remains sadly so in the public persona among Germans vs. Poles:
Bleibt dein Wagen noch gestohlen,
Such ihn wieder mal in Polen!
(Is your car one more lost soul?
Chances are it's with a Pole)
The social and cultural 'avocation'/vocation appears, as always "thief ", placing them just one rung above the Turks and the Russians on the German social pecking order:-(((
