It's varies in different parts of Poland.
Lublin - double fine for crossing a street with an "island" between the lanes on red light
Warsaw - single fine, but ~99% chance of getting fined even if you don't see any cops around
Gdańsk - you can jaywalk in front of a precinct and unless you force drivers to honk, or act stupid in other way - no cop gives a flying fuck. Cities with tourism have cops acting on different rules.
As an American, I had to do the math on that -- which is really annoying.
If you want to provide us with something we can understand, it's furlongs per fortnight, not per minute. ;)
