Vice President Joe Biden bumped into the boss during his vacation in the Hamptons this week. At Flying Point Surf Shop, Biden, casual in shorts, caught a young sales clerk who just happened to be wearing an Obama Halloween mask. When the flustered teenager saw the vice president, he ripped off the mask and threw it on the floor. A witness said Biden laughed it off as he browsed the Tommy Bahama gear. Biden was spotted the following day at Hamptons hot spot 75 Main lunching alone on a hamburger and iced tea. The White House didn’t get back to us.
