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.
Kissing
When close friends greet each other, it is common to kiss both the left and right cheeks. However, this is considered inappropriate in a business setting.
Knocking
When entering an office, it is common to knock first and then enter the room immediately.
Birthdays
You do not have to throw a party for yourself, but if you do, provide food and drinks for all your guests. (In return, they’ll give you presents.) It is also common to bring some cake for your colleagues on your birthday.
Closed doors
Germans enjoy quietness and privacy. They may thus often close their doors but will be happy to receive you if you knock on the door. A closed door doesn’t necessarily mean that the person cannot be disturbed. Likewise a closed bathroom door in somebody’s house does not mean the bathroom is occupied.
