Saunas, a minority of swimming pools and even some public parks on sunny days are considered to be "textile free," at least at particular times.Getting together completely naked in a sauna, however, has no sexual dimension to it whatsoever.Garbage: Germans are extremely environmentally conscious and separate their garbage to facilitate recycling.
Punctuality: Don’t turn up late for an appointment or when meeting people.
Germans are extremely punctual, and even a few minutes’ delay can offend.
But if you feel you would be uncomfortable, it may be a good idea to ask first before you join a trip to the pool.
This attitude spills over to television, where the programs and even the commercials can feature more nudity than is the case in most countries.
These days, rather than being seen as polite, it can be offensive.
Just use the normal "Frau Müller." Nudity: In Germany, you might be confronted with a much more tolerant, open attitude to public nudity than might be the case in your home country.
For some cultures it is uncommon to see teenagers order a beer at restaurants and pubs.
Remember that the legal drinking age in Germany is 16 for beer and wine and 18 for spirits.
Flowers: Bring flowers if you’re invited to a German home for some social occasion.
If the flowers are wrapped in paper, remember to take off the wrapping just before you enter the home.
Greetings: When customers enter shops, especially smaller outlets, they greet everyone in the shop. So practice saying "Guten Tag" and "Auf Wiedersehen." Seating in restaurants: It is common to share tables with perfect strangers when restaurants are full and very busy. Also, wish the other diners at the table "Guten Appetit." But don’t expect any further conversation at the table.
