I bow to the superior being! *GGG* Yes, this use of the word "schnitzelbank" brings most sense into all that...
I had just imagined the "wrong" use of "der" instead of "die" was degenerated dialect influenced by the english-speaking neigborhood. Or a cut in order to fit the word into the metrum like in "Es ist ein Ros` entsprungen".
About the "Hobibank" version: maybe the origins lay in the southwest, but it is as typical it can be for bavarian folk. Thats all I can say about it.
