hi there,
German is the official language. Austrians tend to be quite formal in social gatherings. They do not use first names when being introduced for the first time.
Handshaking is normal when saying hello and goodbye. It is considered impolite to enter a restaurant or shop without saying Guten Tag or, more usually, Grüss Gott; similarly, to leave without saying Auf Wiedersehen can cause offence.
If invited out to
dinner, flowers should be brought for the hostess. The Church enjoys a high and respected position in
Austrian society, which should be kept in mind. It is customary to dress up for the opera or the theater.
Hope this helps
