This scene represents exactly Peter Parker in these films, a gentle man who lets people shit on his head, the fact that this scene is repeated over and over again just shows how this is repeated with Peter all three movies, at no time do we have a evolution of him, at no point do we have him letting him be this idiot that lets everyone take advantage of him, whereas in the comics, he became more self-confident and less awkward after all those years of crime-fighting and doesn't let anyone push him around.
