BUFFY’S VAMPIRE-PROOF LUNCH

Vampires NEVER eat lunch with Sarah Michelle Gellar! As she snacked with fiance Freddie Prinze Jr. at Barney’s in BevHills, the “Buffy” star heard a lady at the next table ask: “What’s that she’s eating?” Said the waiter: “It’s a chopped liver, onion and egg bagel sandwich. You want one?” Snapped the lady loudly, “NO! . . . It looks DISGUSTING!”
