Title inflation, Italian style

A short post script to the last post: whenever I am in Milan I go to a small cafe near the library here.  People there are very nice and always greeted me 'ciao dottore'. That's until they found out that I actually have a PhD, which is when they started to say 'ciao professore'. As I said, they're very nice and generous people. But I wonder what they will call me if I ever make professor.
