fucking what?
1st. Sanji's CoO can only hear women. Not men's footsteps.
2nd Why would Sanji exhaust himself by going invisible if he had no plan and and just happened to be lucky for prostitute appear?
3rd
Queen's neck is nowhere in the middle. When he stands, sure it's somwhere in the middle
but when he started running like naruto run, he extended his neck forward
This is such a stupid cope that somehow squeeking floor told Sanji where Queen's neck is and even it's heght. Not to mention the fact that Sanji was exhausting himself for no reason then if not for the prostitute.
