- No small talk in shops. There are other people waiting and the cashier doesn’t care about you unless you’ve known each other for years.
- No small talk in general, particularly in public transport. Same reason. Although there are exceptions of course.
- Do not smile at strangers. It’s disturbing. Smiling at a stranger is only okay if you hold a door for someone or something similar like that.
- Do not use first names with strangers unless it is explicitly stated you can do so. No first names in proffesional setting unless stated otherwise. If a person older or of higher position than you calls you by your first name, it doesn’t mean you can do the same to them.
- Take your shoes off inside.
- Do not talk about your religious beliefs. Most of the population is not religious and will not care about that kind of conversation (obviously unless both of you decide to talk about it. Just read the room.)
- Do not mix your beer.
- Academic titles matter, do not adress anyone “professor” unless they have that title before their name.
- Do not ask for an extension without a good reason. It is not a normal thing here and will not be appreaciated.
- Do not under any circumstances adress your teachers by their first name.
