As a Brit I was surprised when I received a reply on Twitter to a blog post I wrote [0] that said:

  ...in Germany nearly 80% of transactions are still cash - lots of places that simply don't take cards

Reading this thread that now makes more sense. We have it pretty good in the UK with contactless and chip & PIN (although I hear the Dutch have it better). I always feel the US is so backwards when I visit and they do the stripe & sign thing.

However, I still think there are many reasons cash should always be accepted. I won't repeat them here as they're covered in the post.
