Some believe that "Italy is not a tipping culture" and that if I tipped "it would ruin it for both Italians and future travelers". To that I respond that if someone is working, they probably would appreciate a tip for outstanding service as a gesture of my appreciation.  I have been to Italy 6 or 7 times over the past 20 years and never had a tip refused, or had anyone act like it was unexpected. They were appreciative. In fact, we just returned from a trip to the Amalfi Coast, Pompeii & Herculaneum, Florence, Greve in Chianti, and Bologna.  I tipped three different private drivers and a tour guide.  They were all wonderful, friendly, and provided a service that we valued.  If it upsets those who don't tip when in Italy, then so be it.  As mentioned above, I let my conscience be my guide in this regard.
