"Every glass of beer gets one or two large olives with a pimento in it, and we call it a beertini," Tavares said. "The object is to work down to the olive."
The line for the popular drink often more than 15 people deep. "People love the beertini," event co-chairwoman Sherri McGinnis said."

Seriously???? I mean possibly a grosser thing would be if the olive were replaced by rat poison but short of that, it's hard to imagine a grosser drink.
