Every stop is still pouring when you walk in, with at least 25 minutes of its happy hour left. A walk is the straight line plus a quarter, at 84 meters a minute, and never more than 8 minutes. Evenings go in order of their walking, in three-minute steps (up to 2 minutes, 3 to 5, 6 to 8 and so on); within a step the cheaper evening leads, adding up the lowest drink price at each stop, counting no shots, drinks with no alcohol in them or rounds sold as one thing, and the middle of the board's prices for a bar left without one, then the one with more stops checked in the last 30 days, then the better rated, then the one trying more kinds of deal, then the shorter walk.
