On the other hand they still had 3 more hours to send their tax declaration when I took this photo (yep, it was 9 pm today and you have to send it before midnight). There are rumors that last year there were people in Jindrisska post office at 10 pm just starting filling the forms. Personally I think those are not rumors...
Well, good thing is that due to changes in Czech tax law I had to pay much much less then I had expected = more money to buy unnecessary things :)
