Angry mad businessman talking on cellphone in office. enraged furious employee, entrepreneur, office

In a brightly lit office, a man with a beard and dark hair wears a blue shirt and passionately talks on his cell phone. His hand gestures emphasize his points. He is seated at a desk with a computer, keyboard, mouse, and a notebook with a pen. The office includes shelves with books and other desks. This would be great footage for advertising technology, talking about working with employees, or discussing business.
