Lawrence Journal-World reports that Panhellenic at the U. of Kansas ("KU") is likely to take action to boycott a local third-party vendor. The sororities accuse the vendor of allowing underage drinking and charging a premium if a certain amount of alcohol is not sold at an event.
The Panhellenic president is quoted, as is a former social chair for one of the chapters.
They cite concerns for members' safety and for potenial liability.
