Other mistake: The apartment is technically supposed to be right over Jack's bistro (a lone apartment by itself), but whenever the front door is open, there are other apartments and a presumed hallway showing. Also, if this IS supposedly the only apartment over the bistro, how is it that it is a completely different looking apartment than the original one shown in the Three's Company episode where Jack caught Mr. Angelino attempting to cheat on his wife?
