The point was to imply that it's your stuff, your responsibility, and the people who work there don't necessarily give two craps about what happens to your luggage.
Heck, we have some admitting they'd give worse service intentionally - you know, things that would get them terminated if their employer found out.
So no, I don't think my death glare was even noticed, but my luggage also wasn't just left sitting alone in the middle of the busy lobby for a long time because I watched it until the "little person" did their job the way they were supposed to a full 20 minutes prior.
