I would only give this half marks. Telling the blind man to feel the letters is a distraction. The letters might not even be on the blind man’s side of the glass. Plus it can be hard to make out letters by feel alone, especially when they’re large.

It also never actually explicitly tells the blind man to pull to open the door! What if he can’t figure out what the letters say and gets frustrated? That would be awkward and embarrassing, something people try to avoid if they want to help someone.
