The seemingly automatic and unexplained use of the informal "Du" (you) with other people is not only impolite, it also demonstrates a lack of sensitivity. They want to appear particularly empathetic by using "Du" to express, "Hey, we're friends! Everything's easy between us!" And that's precisely what isn't empathetic.

 It's actually a form of degradation and disrespect. While addressing someone informally signifies closeness, friendship, sympathy, and equality, this doesn't mean that using "Sie" (the formal "you") automatically negates all these positive qualities or creates a sense of superiority or cold distance. It's entirely possible to be closer to someone with a respectful "Sie" than with "Du."

There are a few facts about using "Sie" and "Du" that can help you appear confident and poised in all situations. Generally speaking, it's considered proper etiquette to use "Sie" with adults AND young people once they enter the workforce. This applies to both private AND professional situations, in face-to-face conversations as well as in phone calls, letters, and emails.

And it continues until a mutual offer of the informal "Du" (you) has been made and accepted. 🙂
