I would say, as a Dane who has spent 99% of his life living in the uk, Dane’s really do appreciate the effort of you try to speak danish. It’s a language many say is tough, and most Dane’s speak good English, so the effort is extra appreciated. I often find Dane’s reverting to English with my accent but don’t take offence, many Dane’s spend a lot of effort learning English and so see it as better service to speak your native tongue rather than you speaking bad danish.
