Debi Pearl touched on this in her book Created to be His Help Meet, and as I recall she puts it like this: The relationship mirroring that of Christ to his people is that of the husband and wife, therefore it is within the marriage relationship that woman submits to man. No other man, be he pastor or whatever, has headship over her.
Elsewhere Pearl notes that there are separate spheres of delegated authority, and that the authority of, say, an officer of the court (i.e. the police) is different than that of a husband, but I think we can all agree that OP's asking about the sort of day-to-day interactions in which the relevant authority would be that of the husband. Does his domain become shared with other men by virtue of their maleness? It does not.
But, she would emphasize, the submissive wife must be sure to comport herself so as to bring honor to her husband. That is always the larger imperative.
At the couple of BF retreats I've attended, the wives in the kitchen didn't let me wantonly raid the refrigerator when I had arrived late and missed a meal, but nor did they leave me to fend for myself; they very hospitably directed me to the food that hadn't been put away yet, the location of utensils, etc. — and I was left with no doubt the husband of these women must be quite estimable. (An aside: Isn't it fun to not have to assume that the plural of husband applies when speaking of a group of wives?)
Lest anyone think I'm holding up Debi Pearl as a teacher, I think she'd be the first to demur and point out she's a woman advising women. I just happened to evaluate the book last week as a gift for a certain woman who wants to become submissive and has asked for guidance.
