Show me what you’ve got!
Personally, I was offered a giant plate with lots of different belegte Brötchen last week, beautifully arranged. As a German abroad (and too lazy to make it myself) I wolfed down three pieces with Mett before even looking at the other options. Not even a little bit ashamed. My non-German partner was slightly grossed out.
If that doesn’t convince you, I still have a German liability insurance despite not living in Germany for 5+ years.
Today, I paid for lunch in cash, even though the restaurant accepted card. Exact change. And it was over 10€, but I paid only using coins.
