If you are particular about how a certain task should be completed, please let the person to whom you've delegated the task know what your preferences are, lest they have to do the task over again a few times because you can't communicate.
Everyone who has ever been delegated upon
P.S. On a completely unrelated note - just because you claim to like efficiency does not mean that you are in fact efficient.
(Not that I'm speaking from personal experience or anything.)
