Even the best booths still get something in the paint somewhere.

I've watched numerous paint video's on Youtube as well as watching a few vehicles being painted in person and have to wonder if the last couple feet of the air hose right behind the gun is not a source for junk in the paint? The hose gets drug across the floor, rolled up with dirty hands after blowing off sanding primer dust etc. all before painting, and yet it seems like nobody pays much attention to it?
