A: It's really up to the Storyteller, but the basic rule of thumb is this: what could the character realistically do within the span of a couple seconds? Freebie actions clearly shouldn't be unlimited. For example, a character probably shouldn't be able to drink more than one potion in one turn (unless they're spending their entire turn drinking a couple potions). If you're the Storyteller and you run into a situation where you have a Player trying to squeeze more out of freebie actions than he or she should, I'd recommend setting a limit. Simply tell the Players that you're limiting freebie actions to 1 or 2 per turn.
