Hello! The choices to make hiro's German stilted/awkward were intentional. Not sure about the worker's speech, I had a few german speakers look at it and they helped make it sound antiquated.
Alrighty! Fantastic attention to detail in that case! There's also a solid chance that anything from the Workers that I marked as an "Error" could just be due to the difference in time period, or maybe even my own misunderstanding.
