The Bavarian State Institute for School Quality publishes material that helps pupils choose a career. One checklist prepares them for a job interview. One item reads: Ich habe die Anreise zum Betrieb geplant und werde pünktlich dort ankommen (Tipp: ca. 10 Minuten vorher). I have planned my journey to the company and will arrive on time (tip: about 10 minutes early). For the case where something still goes wrong, the etiquette coach Elisabeth Bonneau gave advice in the Tagesspiegel. If public transport fails or a bicycle tire bursts, one should auf jeden Fall anrufen und Bescheid geben, in any case call and let them know. If nobody answers, one should leave a message.
