Try Schengen to non-Shengen at AMS.. there is no fast connection lane like there is from non-Schengen to Schengen..

Trouble is, training and organization are to blame, not the person themselves (most of the time); and when you make a scene or get rude you're just being a dick...

I get really pissed off about the endemic incompetence of ServiceAir and LBA Airport generally, but it's is the organization and training that is at fault not the person. Being rude helps noone, and certainly won't resolve your problem any quicker.
