I have arranged for a driver to transport us from FCO airport to the cruise terminal.They are charging 110 euros. How much is the appropriate amount to tip the driver?

There is no set tipping schedule. Most Italians might not tip at all. Most Americans would tip.

Personally, if I liked the person, and the service was great, I would probably tip 10 euro IF the person worked for a car service. But NOT if this is his own car and his own company.

How much luggage do you have and do you expect the driver to deal with it? If someone is hauling your luggage around, versus just drivig you somewhere, they definitely deserve a tip.

Also - is the driver self- employed (tip for luggage only) or employed by a company - I would tip.

As I understand it, all drivers are entrepreneurs, in that they own their cars and have acquired (expensive) licenses to operate them as "noleggio con conducente" (hired car with driver).

If they "work for" a car service, it merely means that the car service acts as intermediary between drivers and passengers and probably charges the drivers a commission of some kind. So it's not really a question of employed vs. self-employed; they're all self-employed.

That said, I'd still tip about 10 Euro if the driver was courteous and punctual and helped with my luggage.
