Servus from Munich: as you may know: Munich is now the most unfriedly city in the world. This comes from a Mix of the Grantler, Mia San Mia and Schickeria culture. The first is the traditional grumpy nature of the typical Bavarian (especially Oberbayern). Sone say this is because of the Föhn wind (warm, dry downdraft that occurs on the leeward side of alps mountains) which can cause headache and paired with a massive beer consume even more. Mia San Mia and Schickeria is only typical in Munich: Many people from all over Germany moved to Munich in the 60s and 70s and earned money and build up an extreme snob culture seeing theirself as better as the rural people in Bavaria.
