Completely agree. I don't want to be that guy in the breezeway further from the BP scanner having to cross over in front of the general pax trying to board. This would make it less confrontational.
There was only one scanner at my gate at LGA a few weeks ago - I stood at the front of the breezeway line and the GA stopped boarding the unwashed masses, came over, took my boarding pass, scanned it, handed it to me, and went back to boarding the unwashed masses. Who cares about confrontational - I'm never gonna see these people again.
