Whether it's a fast food chain or an elegant restaurant with a sommelier pouring your vino, watch out people for a little stringy thingy.   You think a pube or two got there by accident?   Think again.   On the latest episode of Tip Not Included, Host Eric Levine talks "Servers Revenge" and highlights the myriad of ways Servers (and Chefs and Bartenders) get even with unruly and obnoxious customers. Not to mention "the ex" who walks in with way too much attitude and a new plaything.   If you over-patronize your server, as Levine points out, that decaf may be regular coffee, and that veggie burger probably came from Elise the Cow (and by the way, may have been kicked around before being put on the bun). That colorful cocktail you ordered? Well, that might have have a little added ingredient inside. Let's just say, the angrier the server, the more the phlegm. Or piss.    And don't be surprised that payback also happens among those working in a restaurant. How about the bartender who was so enraged at a chef that he swooshed said chef's drink glass with a grotty toilet brush before adding a little of his own pee (for added flavor, of course).    Which takes us back to pubic hairs and what else we find downstairs. There's a good chance you've eaten something that was touched by testicles . . . Guys in the kitchen probably find that a thing. In Levine's research, he found no food was touched by a woman's anatomical counterpart.    His fact finding continues though, and he'll surely be offering updates on future episodes.   To contact Eric Levine, write to him at: [email protected]
