There are some mistakes in your article:
It's 1/4 of minimal wage so now it's 500 zł.
You need a permit but it's not counted as weapon.
You can book online at Polish legal bookies.
You can trespass on someone land but only if you repair all the loses later.
Every building must have a number. Not apartment.
Thank you for the follow-up. Next time i will check twice such things :)@lukmarcus
