If you ever find yourself heading to an over-crowded public loo, (most likely at the theatres, bus-stands, expressway food-malls, railway stations or on the rarest of occasions, perhaps a public loo along the way when you're running the Mumbai Marathon,) here's a tip that'll probably help you find a booth the fastest.
Always line up behind the booth occupied by the skinniest guy there. He's bound to be done the fastest! After all, he's slim, so he'll be able to unzip and zip up faster, (his clothes, are obviously likely to be easily maneuverable,) ((and he'd probably be able to handle his tool the best too...after all, there's gotta be little hiding the view from him right?))
DISCLAIMER:> Nothing personal against the not-so skinny ones! :P
