The man walked into Antonio's in the college town of Amherst early Saturday morning shortly after Dylan performed at the University of Massachusetts and ordered $3,900 worth of pies.
He said he would return in several hours and deliver them to Dylan's crew. But he never returned and the manager called police.
Restaurant employees stayed until 5:30 a.m. making the pizzas.
Antonio's owner Walter Pacheco tells The Daily Hampshire Gazette his workers had no reason to doubt the man worked with Dylan but "got taken."
Pacheco said he gave some of the pizzas away, but had to throw out most of them.
