As a quick aside, avoid relying on any distinction between the terms "morality" and "ethics". I don't think there is any coherent, universally agreed-upon difference and inventing one tends to lead to confusion.
Community norms are inherently an appeal to (diffuse) authority, yes, and have little explanatory power; hence my noting it as a non-answer in the comment you linked to. Nevertheless, the norms objectively exist even if their foundations may be arbitrary.
The "real" answer, from my perspective, is that it's still a (mildly) inethical way to interact with people, but some combination of your "its part of his job" and a more general argument for impersonal economic transactions providing social benefits in the big picture outweighs it in many cases. On this basis, I accept the status quo of the afforementioned social norms.
Thanks for that clarification!
morals/ethics: I probably read your definition of social acceptability in terms of ethics backwards.
I think that you're too trusting of society's verbalization of morality and that this is rather different from what people actually accept. This is similar to the discussion of lying. It also reminds me of Michael Vassar's comment about homosexuality. Even if generally accepted ethics deviate from generally verbalized ethics, it's not clear what to choose.
Disclaimer: If you are prone to dismissing women's complaints of gender-related problems as the women being whiny, emotionally unstable girls who see sexism where there is none, this post is unlikely to interest you.

As far as I can tell, I am the most active female poster on Less Wrong. (AnnaSalamon has higher karma than I, but she hasn't commented on anything for two months now.) There are not many of us. This is usually immaterial. Heck, sometimes people don't even notice in spite of my girly username, my self-introduction, and the fact that I'm now apparently the feminism police of Less Wrong.
My life is not about being a girl. In fact, I'm less preoccupied with feminism and women's special interest issues than most of the women I know, and some of the men. It's not my pet topic. I do not focus on feminist philosophy in school. I took an "Early Modern Women Philosophers" course because I needed the history credit, had room for a suitable class in a semester when one was offered, and heard the teacher was nice, and I was pretty bored. I wound up doing my midterm paper on Malebranche in that class because we'd covered him to give context to Mary Astell, and he was more interesting than she was. I didn't vote for Hilary Clinton in the primary. Given the choice, I have lots of things I'd rather be doing than ferreting out hidden or less-than-hidden sexism on one of my favorite websites.
Unfortunately, nobody else seems to want to do it either, and I'm not content to leave it undone. I suppose I could abandon the site and leave it even more masculine so the guys could all talk in their own language, unimpeded by stupid chicks being stupidly offended by completely unproblematic things like objectification and just plain jerkitude. I would almost certainly have vacated the site already if feminism were my pet issue, or if I were more easily offended. (In general, I'm very hard to offend. The fact that people here have succeeded in doing so anyway without even, apparently, going out of their way to do it should be a great big red flag that something's up.) If you're wondering why half of the potential audience of the site seems to be conspicuously not here, this may have something to do with it.
So can I get some help? Some lovely people have thrown in their support, but usually after I or, more rarely, someone else sounds the alarm, and usually without much persistence or apparent investment. There is still conspicuous karmic support for some comments that perpetuate the problems, which does nothing to disincentivize being piggish around here - some people seem to earnestly care about the problem, but this isn't enforced by the community at large, it's just a preexisting disposition (near as I can tell).
I would like help reducing the incidence of:
