The fact that the stereotype exists (and both the man and the woman presumably know that it does) makes me perceive the comment in the OP as mocking or patronizing. The man’s intent could be to offend or perhaps to imply “I’m glad you don’t actually expect treatment like this,” but even that would offend many women. I don’t understand why you or the woman in the OP think it was said in good faith, because it’s something I would say myself only if I wanted to hurt the feelings of the woman I was speaking to so much that I was willing to sound sexist.
