“This summer, some Boston University students thought they were attending a morning lecture by a renowned cultural anthropologist in an advertising class.” It was actually a shoot for a McDonald’s ad, in which “the students appear tired, dazed, and yawning until a crush of chipper uniformed McDonald’s workers, some actors and some real employees, swarmed into the lecture hall. They served everyone cups of iced and hot coffees. On camera, the students perked up and sipped their drinks.”
