[As a bartender, Luca's job is to people watch back. People watch, and of course approach with a bit of alcohol in kind. He has a jug of wine in one hand and a glass in the other. The latter is extended in offering, but not yet set down.]

You would look far more natural if you had a glass in hand. [His voice is... not quite flat and unamused, but certainly not Excited about Passenger's snooping.] Otherwise, you will find yourself approached by those that would rather not be spied upon.
