Campus Dining Services is currently investigating a case involving a rusty nail pressed into the bottom of a student’s hamburger bun purchased at Wendy’s in Roth Cafe. Sophomore English major Ashley Tymann bought a junior bacon cheeseburger from Wendy’s at 6 p.m. on March 30. After taking it back to her friend’s dorm to eat it, she found the hazardous addition to her meal once she took a bite and a rusty nail fell onto the wrapper in her lap.
