Krispy Kreme apparently needs to graduate to home delivery.

Krispy Kreme’s ‘free graduate dozen’ promotion was forced to end early after a blocks-long traffic jam occurred in front of a store in Long Beach, Calif.

Though the graduate dozen will be available at Krispy Kreme stores nationwide until May 24, it was only available for free on Tuesday, and only for graduates who showed up dressed in graduation cap and gown, or had a student ID, graduation announcement, or tassel that confirmed they were a graduating senior.
