ETIQUETTE AROUND THE WORLD
Punctuality
Gifts
Spontaneous visits
Cutlery
Closed doors
Calling someone on the phone
Noise
In a business or professional context, Germans respect regular business hours, which for most people is between 8 am and 5 pm on weekdays. If you try calling after or before hours, you will be unlikely to reach them.
There’s a reason the “being punctual like a German train” exists. Germans value punctuality and it is expected that you arrive at a meeting 5 minutes early, just in case. If you can’t make it on time, always call or text to let the other person know. 
Compared to countries in Southern Europe, Germans are quieter, and they like it that way. Loud conversations at work, in public transport, or in a restaurant are a big no-no. One famous exception? Oktoberfest.
Do not come by someone’s house unannounced, even if you know them well. Ask them beforehand, call, or send a quick text. They might be busy, sleeping, or passed out on the couch. 
When you are invited somewhere it is expected to bring a little gift for the host. Flowers are common, but wine and chocolate are thoughtful options as well. If you know your host well, get them something you think they will like.
Toasting
Beverages
It is common to have alcohol with dinner, and in some cases even lunch. Accept a drink or two if you want, but don’t feel pressured into drinking.
It is common to toast when enjoying a meal with company – but make sure to look the other person in the eye when you do! It’s considered bad German etiquette and even supposed to bring bad luck if you don’t.
In restaurants, even pizza and burgers are eaten with cutlery. Not using cutlery is frowned upon. When in doubt, mimic the other guests when you are unsure about the use of cutlery.
Crossing roads
Nudity
Germans like their privacy and quiet. A closed-door doesn’t necessarily mean that you shouldn’t enter, or that the person doesn’t want to be disturbed. Politely knock and when the person says herein “enter”, step into the room.
Germans are pretty chill about nude bodies and saunas and beaches usually reserve spaces with a no-clothes policy. When you are in those areas you are expected to also take your clothes off. And the most important rule – don’t stare at the others!
Stop when it’s red, walk when it’s green. Traffic lights are a no-brainer but in Germany, they are taken seriously. Don’t walk over a red light, even if there’s no car in sight, especially when children could see you. This is an unspoken role and violating it will give you a dirty look or two.
