The video of a fellow student berating food service workers who refused to sell him jalapeno-bacon mac and cheese prompted a group of students to start an online fundraiser to give the beleaguered employees a well-deserved night out. The 9-minute, obscenity-laced video clip posted online shows freshman Luke Gatti arguing with and eventually shoving Dave Robinson, a food service supervisor.
