I am a snorer, and thus I try at all costs not to fall asleep on a flight. But I am one who is "guilty" of putting my feet up on a bulkhead with clean and fresh socks. It is difficult to do this with business shoes on.

I usually won't do this if there is someone next to me, but if noone is next to me, who is being harmed. And why are you looking at my feet anyway?
