After his low-key wedding with longtime girlfriend Priscilla Chan, serving sushi and chocolate mice to less than 100 guests in the backyard of their Palo Alto home, Facebook founder and multi-billionaire Mark Zuckerberg swept his new wife away on a secret Italian honeymoon.  They didn’t stay under the radar for long, however. A Polish tourist drew media attention to the Roman holiday after snapping photos of the pair site-seeing. Already, the 28-year-old cash king is raising eyebrows over his reported cash-poor tendencies.  First, the newlyweds were spotted in Rome sitting on the Mignanelli Steps near Piazza Spagna and eating a to-go lunch from McDonald’s. Then, they surprised the owners of Nonna Betta, a restaurant that specializes in Roman Jewish food, by opting for water and tea over wine or beer and not leaving a tip on a bill of 32 euros, despite telling the owner they enjoyed the meal. According to The Telegraph, it wasn’t the first time. They also failed to leave a tip the night before when dining at historic trattoria Pierluigi in the heart of Rome.  The young tycoon also seemed confused over how to withdraw money from an Italian ATM. On the island of Capri, an onlooker captured a video of a perplexed Zuckerberg becoming flummoxed by the machine, asking for help and ultimately walking away empty-handed.  While the couple enjoy their European adventure, shares in newly public Facebook continue falling. On Tuesday, it closed at $28.84, a 24.1% drop from the $38 IPO price.
