Short and fat
I once watched two short fat girls trying to stuff full sized pillows (WTF?) into overhead lockers.

If either had been slimmer they might have got close enough to reach the locker. If either had been taller they might have done it. Cabin staff had to do it for then as they were blocking the aisle.

Then there are those who are on their feet as soon as the plane stops. There's no prize for being first off.
