> To give an analogue in the English language: you wouldn't address your boss with "yo n"

Not even close, not even close. Why would you even write this? This must be a dog whistle.

Edit: that link you posted justs lists the €600 as "this happened once and depends on income of offender", also there is no source.

In addition, the intro paragraph says

> Es gibt jedoch bei Beleidigung keinen „Bußgeldkatalog“. Vor Gericht wird der Straftatbestand der Beleidigung verurteilt.

which translates to there is no schedule of penalties but it all depends on the statutory offence. So my understanding is there was a criminal offence that included an insult (saying "Du") which was mentioned in the report but not the cause for the fine in the first place.
