Social notworking billionaire Mark Zuckerberg shocked the Romans for being such a tight arse.
The press here is all a flutter that Zuckerberg had a honeymoon lunch with his new missus, Priscilla Chan, in the historic Jewish quarter and didn't even leave a tip.
The price of the lunch was just 32 euro, which for a tourist trap like the Jewish quarter in Spring is next to nothing. Some restuarant owners in Rome have been arrested for charging tourists hundreds of euro for next to near nothing.
What surprises the Romans is that the Americans are famous for being generous tippers it makes up for the fact that they often stroll around Rome shouting about how old everything is.
Zuckerberg is not short of a bob or two so the waiters started planning to go somewhere nice in August when Mr and Mrs Zuckerberg left without leaving a tip.
All that left the poor waiters at Nonna Betta, which specialises in Roman Jewish cuisine to tell their chums at the local media.
For the record it was a good lunch deal - deep-fried artichokes, fried pumpkin flowers and ravioli stuffed with sea bass and artichokes. It appears they saved loads by having a bottle of water and a pot of tea.
"I asked him 'how was it?' and he said 'very good'," the owner, identified only as Umberto, told Corriere della Sera newspaper.
The couple's Roman adventure was supposed to be closely guarded secret until a Polish tourist spotted them in the Sistine Chapel, snapped a blurry photograph, and posted it on Twitter.
It seems that Zuckerburg must have heard about his company's share price dropping down the loo while he was on his holidays and decided he should be saving a bit of cash.
