Can I complain about seatmates who in a coach seat are acting like they are in a personal office cube? Laptop out, elbows intruding, lifting laptop and tray while trying to grab another file out of bag underneath, drink perilously balanced on lap which I hope isn't going to spill on me or my bag. Better yet, already set up in this configuration in the aisle seat during elite boarding and giving an eye roll and exhaling an annoyed breath when the window seat and/or middle seat show up.
