This upping of the ante represented by McDonalds’ latest ad (and by guerrilla marketing generally) exacts a terrible price, one well beyond that of a venti McSpresso. It induces a form of epistemological vertigo that comes when we can no longer trust our own experiences, when we innocently sign up for a course and are made complicit in a spectacle that will earn millions for the company advertised, while we walk away with only crap-ass swag and lattè-foam moustaches for our trouble.
