Pyro did it

A man in a white lab coat reacts with wide-eyed shock and then screams while holding his head, as a man in a blue uniform and cap sits at a table, initially looking distressed while holding a bucket of fried chicken, then smiling as chicken pieces fly out of the bucket and he looks at the camera. The scene takes place in a dimly lit room with tiled walls, a counter, and a sign indicating "5¢" and "TRESPASSING WILL BE PROSECUTED."
