Vienna cafes seem designed for whiling away an afternoon without a smartphone. Their 'shoot - review - shoot again' pattern seemed like a teacher - student relationship.
@kali66 Good one. I hadn't thought of that. At the time I had a vague recollection of a surrealist portrait of a man in a hat with a similarly draped face. Then I noticed the subject chose to sit under a print by the surrealist painter Gustav Klmit. Maybe his choices were an homage to the surrealists?
