The Scientist in Me
No that isn't a reference to a particularly intellectual homo-erotic practice, just I couldn't resist washing the hands in aforementioned washroom and experimenting which dryer would actually dry a hand quicker
a) Dryer #1: The fast blowing arctic temperature blower
b) Dryer #2: The pathetic puffer of warm air

Result... initially Dryer #1 was seem to dry the (left) hand faster than Dryer #2. On leaving the washroom, it seemed both had been equally unsuccessful and that Dryer #1's perceived success was due to the numbness induced by the -20deg c wind chill factor.

Odd look from fellow patron as I stood there with one hand under each dryer... nothing was said.
