>I was not referring to such an environment.
I know. But it was me who referred to those tiny differentiations
of the colloquial Hochdeutsch, since even in the most "neutral"
kind of it, there are (phonetical, lexical, grammar) peculiarities
that represent additional information on something of the
speaker's geographic and social background. And among these
peculiarities, there are also some typical mistakes (but not
the same mistakes made by foreigners).
