The lady who says she bit into a severed human finger tip while eating chili at a Wendy’s restaurant has a troubling history of filing lawsuits–including a case against another fast-food restaurant. Meanwhile, cops are continuing the search for the finger tip’s owner, including an investigation of the accuser’s home. Now, she’s whining that law enforcement officials trying to get to the bottom of the case are treating her family like “terrorists or something.”

The story has provided a lot of late-night comedy fodder. But to Wendy’s, which suffered a sharp sales decline after the incident was reported, getting fingered by a serial litigant is no joke.
