A Question About An Accent?

As a native speaker of English, I know many will disagree with me, but I think accents are colorful and beautiful. They sound more authentic. However, to foreign speakers, it may be somewhat annoying because they find it hard to understand. I speak German, but Swiss or Bavarian Germans are very hard to understand even when they speak slowly with their dialect. And having to ask someone to repeat every sentence three or four times is very annoying.
