Maybe I'm filthy, but I've always just patted the back of my shirt unless I'm in a place with clean cloth towels available. It's not the outside temperature that'd discourage the already apparently slim number of people that do bother to wash their hands. It's water temperature. And if the water is freezing, no drying method will get the average joe to endure the pain of water hitting their hands.
