Sorry folks but the Poles are a Nation of liars. When you have an appointment with them or any kind of transaction which involves a Pole when they realise they cannot keep their side of the bargain they lie their way out of it rather than tell the truth ...
Much of this can be attributed to the overwhelming preponderance of Roman Catholicism in Poland. Turning their backs on the Bible, the Polish natives stumble about on the shifting sands of moral relativism with little regard for the consequences of their actions.
Of course, they reap what they sow, as history has demonstrated time and time again.
