In their defence, and possibly at the risk of appering a fool myself, the first time that I sat in row 3, I suggested to my wife that she could put her handbag under the seat in front. I assumed (and when standing, it looked like) the footwell (which is black) was actually a cutout and space under row 2 was accessible.That doesn't explain a total lack of knowledge about where to store carry-on when there is no seat forward of them!!!!
