Facebook billionaire Mark Zuckerberg is a lousy tipper?

Mark Zuckerberg is no friend of the service industry, or so it seems. 

The billionaire Facebook honcho spent the New Year's holiday in Maui with his wife, Priscilla Chan. Now an insider at the Four Seasons is spilling the beans on the social network boss' cheapskate ways.

"Mark is a nice guy but far from a big tipper," the tipster tells Star magazine. "He certainly wasn't sharing the wealth."

Zuck reportedly pored over his bill in great detail at checkout time, going so far as to dispute a charge for a $5 soda. Pinching pennies must be how Mark holds on to that $14 billion net worth.

Wait, was Ebeneezer Scrooge an economics professor at Harvard?
