That happened to me once at the university pool. Well, the gentleman was just older, and bigger, not "very large elderly." But I was quite annoyed, stuck behind him in the medium lane where he clearly did not belong with his very slow, very precise breaststroke.

After a bit, I was about to say something to him when I realized it was actually my supervisor! He did not have his glasses on, and he never knew it was me. I just passed him.
