I agree with the unfriendliness aspect in German government offices. These people are a very particular sort and they can be curt and borderline crude even to German nationals.
In addition, no mortal is able to fully understand the German tax-system, regardless where you are from, which can easily run you into trouble by itself, for sure even more for non-native speakers.
