... oh, that's because a fair few of them are German dental clinics .
The interiors are almost all one of two similar styles. Style 1: curvy plastic like the inside of a 1970s futuristic spaceship, but chunkier. Style 2: cold minimalist small ware house with really expensive materials to make the interiors look like they were artistically designed.
Seriously, the interiors would be genuinely off putting to an anxious patient who was already a little disorientated. Very little text; just a picture book as you would expect.
On a more pleasant note, most of the architects were actually *smiling* in their mug shots!
Too, in America, dentists do not have their own rooms, but the chairs have a thin divider between them! How weird is that! Even in apparently high tone offices!
