Of course you shouldn't include prostitution in the same group as waitress.......but was there really no job to be had, not one, in over a year in Berlin? Sounds like a screwed up policy/law is catching up to someone who really just wanted to ride on unemployment benifits.
I guess I just placed Berlin in a group of first world cities without knowing what I was talking about. I tend to be be biased regarding unemployment in major US cities.
Germany is currently in a major recession / minor depression, so I think it's plausible that there weren't any jobs available for over a year.
