Prepare for people to speak with quite an accent. Drugs (Cigarettes, most Alcohol and Weed) are allowed from 18 y.o. Even though weed is kinda legal in germany for some reason Bavaria decided to be increadibly strict about it, so I'd advise to steer clear. Obviously Nazi paroles and insignia as well as the Hitler-Gruß are illeagal.
If people are hellbent on speaking German with you, which I assume you do not speak, here is a handy phrase:
- Ich spreche kein Deutsch, aber ich spreche Englisch.
- I do not speak German, but I speak English.
English is taught from a young age, so you'll find many people who are able to speak it.
When in a pinch you can approach people to ask for i.e. directions. This includes police officers, should you see some. They'll usually will be happy to help.
In an emergency, means . It is best to point or directly adress a single person when asking for help to ensure they'll jump into action.
Emergency numbers are 110 for police and 112 for firefighters/medics. But 911 also works. I'd like to add that these services are usually free, no need to fear a transport by ambulance for financial reasons.
