In the situation described in the comic, I would ask “need help?” out loud without moving towards them until they say yes (where by “would” I mean ‘recommend’—not sure what I would actually do in such a situation, due to akrasia).
With doors, when there’s someone close but not that close, I push the door forward and move on, so that (if it’s slow enough) it will still be open by the time the person behind me arrives.

I sorta prefer a closed door to a door swinging toward my face.
