I have always thought the best stewards are the ones I rarely see. My room is magically refreshed while I am away. If I have no issues with remotes, ice, toilets, tv or whatever, I don't need to see a lot of them. (You would be surprised how good they are at fixing tvs when there are issues.)
Happy to say hello in the hallway when I see them, but generally I don't need to learn their life stories, nor they mine.
Others really enjoy engaging a lot with them...different strokes for different folks....
