I’m not entirely sure what the worst part is of this collection of signs – that they had to show their ban on pooping in the parking lot so visually, or that the fine (Bußgeld) for messing up things is a whopping EUR1533.88 ($2100).
If you are wondering how they got such a weird number for the fine, they simply converted it from DEM3000 (Deutschmarks) to Euros during the conversion. That is much more democratic than simply rounding it down to EUR1500.
I’m guessing the funniest thing is the combination of all of the above, along with such insanely long words as “Ordnungswidrigkeitsverfahren”. Try saying that a couple of times.
