I'm not sure whether you're interested to know that some FBOs are very good and help and assist in a way that gets you in and out of an airfield with little or no stress. However there are some, and I have to say it, in Italy that have little or no idea what being an FBO is all about. My recent flight to Greece and back showed just wide the gap is between the good and the bad.
Lack of preparation and lack of foresight and generally untrained are the hurdles that I faced when landing to get a refuel. How refreshing it was to return to UK airspace and have professionals in the FBOs.
