Language
German is the language, with strong regional accents (Bavarian, Swabian, Saxon) that even Germans joke about. English is widely spoken in cities, hotels and by younger people; older people, rural areas and the former East speak less. A few words of German — Hallo, Danke, Bitte, Entschuldigung — make service friendlier.
- Use 'Sie' (formal you) with adults you do not know; 'du' is for friends, children and younger people in casual settings.
- 'Bitte' means please, you're welcome and 'go ahead'; 'Bitte?' also means 'pardon?'.
- Signs you meet on day one: Ausgang (exit), Eingang (entrance), Gleis (platform), Abfahrt (departure), Kasse (till).
Etiquette, safety and scams
Etiquette
- Greeting: Firm handshake with eye contact; 'Guten Tag' or 'Hallo'; avoid: Hugs with people you have just met
- Names: Herr / Frau plus surname until invited to use first names; avoid: Using 'du' with officials or older strangers
- Punctuality: Arrive on time for tours, dinners and appointments; avoid: Being more than 5–10 minutes late without a message
- Queues and rules: Follow signs, wait at red lights, sort rubbish; avoid: Walking in cycle lanes
- Conversation: Direct and factual; people say what they mean; avoid: Taking directness as rudeness, or joking about the Nazi era
- Home visit: Bring flowers (odd number, not red roses) or wine; shoes off if the hosts do; avoid: Arriving early
- Paying: Say the total including tip as you pay; avoid: Leaving coins on the table and walking off
Scams and watch-outs
- Train service is only S/RE regional; check schedules for late returns
- Aggua sauna is women‑only on Monday mornings
- Museum opening hours not listed online; verify before visiting
