Other mistake: In Abby's scene when she is required to bring refreshments to the meeting room, all the drama happens because there's a chair blocking her way to the left of the table. Any sane person would just walk to the right of the table. She has all the space in the world to do that, but the plot to work she appears to be unironically too stupid to even consider the possibility. She also has room to put the tray down without moving a step. (also, as a bonus, the hand of one of the guests is embedded inside the table, just the thumb sticking out).
