Significance of the glove in the elevator?

I thought the elevator scene was great, simply because it gave Joubert a personality. Movie killers are typically cartoonish, 2-dimemsional, anti-social thugs. Joubert was polite, civil, and engaging, even with one of his targets. In a lesser movie, Joubert and Turner would have just rode the elevator in awkward silence. Instead, Joubert is friendly, disarming, even, despite the fact that he's tasked with killing Turner. Joubert is smart enough to wait until the most opportune time, and it's not in the elevator. So, he simply acts like any other polite stranger might act in the same situation.

In fact, it just occurred to me that the kid who pushed all the elevator buttons might actually have saved Turner's life. If he hadn't, Joubert could have conceivably had enough time to kill Turner in the elevator before the doors opened at the ground floor. But with the doors stopping at every floor, well, Joubert knew it might not have been the cleanest assassination, and just waited. It also explains why Joubert got in the elevator, at all. Otherwise, why didn't he take the stairs, beat Turner to the ground floor, then get a shot at him outside without Turner knowing he was there?

Regardless, I like Max Von Sydow's Joubert as one of the best movie villians, or at least, assassins, right up there with characters like Pulp Fiction's Jules and Vincent. Just the polite way he speaks, from telling Turner's girlfriend to "Please move away from the window" to the European way he later tells Turner "Please to set the gun down on the desk" and, later, when he tells Turner about returning to NYC, "You have not much future there". The way he uses the infinitive version of the verb 'to set' rather than the simple imperative is a small, but noticeable, part of it.
