Women's Liberation?

Ned has often felt, with the greatest respect, that some of his friends and associates among the female persuasion always wanted to have their cake and eat it, too: they wanted all the trappings of equality, whatever that means, without really wanting to deal with all the responsibility that goes along with it. And to illustrate this, Ned will tell a tale.
It was many years ago, when Ned was a young and foolish unmarried college professor, and if he does say so himself, in some demand from his female friends. One day, an associate at the College, not someone Ned knew well at all, made a startling request: would Ned take out his sister-in-law, who was visiting town for a few days, and who was down in the dumps because she was going through an unpleasant divorce? More out of curiosity and the inability to think of an excuse to refuse, Ned accepted. He drove to the person's house, and picked up the female--an average person but pleasant enough. Ned took her to one of his hangouts, the local Sheraton, where they had a decent happy hour, and ordered drinks: she having a vodka and something, Ned having a beer. They talked about unimportant things, and Ned knew he was really not interested in following up this chance encounter, but certainly wished the woman well. They had another drink and a bit of food. After another hour or so, Ned asked if she was ready to leave, and ordered the bill. 'Shall we split this?'
'Oh' was her reply, 'I didn't bring my purse.'
Now, Ned would like to ask his friends to imagine Ned's ire rising: this woman, who had never met Ned before in her life, and for whom he was essentially doing a favor for an acquaintance, had simply assumed that, whatever the cost of the evening, it was Ned's responsibility.
Ned drove her in silence back to her brother-in-law's house, opened the car door for her, she got out and that was that. But ever since then, Ned has been suspicious of all those who profess to believe in the 'absolute equality' of the sexes, because he doesn't believe that some women really accept all that goes with it.
Now the more cynical of Ned's associates might well ask: what would Ned's response have been if the woman had, shall we say, evinced an interest in an urgent physical intimacy? Ned shuns the implication, and replies that there are words for persons who are willing to trade sex for food and drink.
