If intern is making a breakfast, and boss is the one who suddenly runs to the grocery store because eggs are missing, is boss still the one in a driver’s seat?

From the original goal point of view yes, as it was boss who has initiated whole breakfast procedure. But from an execution standpoint it is intern who gives its boss a job of a grocery store run. He could give same job to anyone else, boss as a persona is irrelevant here.
