This happens most often in adverts for a type of service (phone, delivery, store, etc) but can apply to products as well: The brand name and its competitor(s) will be represented by employees of the respective companies, usually low-level workers such as cashiers, stockboys or delivery drivers. When the shortcomings of the competitor are inevitably brought up, they are pinned directly on that company's employee -- as if to imply that this minimum-wage grunt is actually responsible for company policy. Sometimes the employee will be a Jerkass and/or fanatically supportive of his employer's policies, thus justifying everyone's ire; but he is as often as not an innocent scapegoat, which can inadvertently turn him into The Woobie.
