Not in Vienna :-)
Back many years ago when I lived at my parents place I seriously had people asking for Herr Professor Doktor Dimplom-Ingenieur Fatherofhch on the phone.
Oh I remember those days...
Happened in the early 90s, when I was a little engineer and my sales manager was almost kicked out of the door of the AKH in vienna. I finally stepped in verbally and used the titles of the professors and professor dr and professor dr dr in a way, that they started listening me and totally ignored my sales manager. My sales manager was intelligent enough to be quiet afterwards and we got the project.
