WAITER, IS THAT SALIVA IN MY SOUP?

WAITER, IS THAT SALIVA IN MY SOUP?

DEL MAR, Calif. (Wireless Flash) -- A former waitress is lifting the tablecloth off what really goes into your food -- and it may leave a foul taste in your mouth. Debra Ginsberg is the author of the new book, "Waiting: The True Confessions of a Waitress" (Harper-Collins), and she claims everything you've heard about servers spitting into troublesome customers' food is true. She estimates about 40 percent of meals served at restaurants are purposely contaminated with everything from saliva in the soup to bread pulled out of the trash. Ginsberg knows one waiter who slurps all over the water glasses of customers who give him a hard time, and she knows other servers who stick their filthy hands into food. And although she's never tried it personally, she says some servers swear that depositing drops of Visine in food slated for obnoxious customers can supposedly trigger a bad case of "Montezuma's Revenge."
