I contend that any decent mafia player should be able to pick their fos within the allotted ten minutes on day one, that taking even a second longer than ten minutes to vote on day one does nothing but hurt the town's chances, and that taking even a second longer than ten minutes to vote on day one makes you an enormous a$$hole who is wasting everyone's time.

If you can't decide who you fos within ten minutes, you have no idea who you fos and you're just guessing, so guess already, loser.
