Chivalry is not dead.
Chivalry has been modernised.
Seeing as how I don't really see the male side of dating, like, ever, I can really only throw in how I handling me dates. Keeping in mind, like TK mentioned earlier, I too am a dating catastrophy.
My version of modern chivalry consists of equal and fairness. That doesn't nessessarily mean splitting the bill, but instead, "I'll get this one, you can get the next.

" Getting a door if I'm right there is fine. I don't think I'd want someone --anyone, reaching before me every time a door barred my forward momentum. I have hands, and the common ability to turn knobs.
(Side note, at work we have these wheelchair buttons at work for the elderly and disabled. It irks me everytime I see someone perfectly able push it rather than open the door of their own strength. Waste of energy, waste of ability, and waste of time.)
I think handing over ones jacket if it's cold is great! But dusting a spot to seat is again, one of those wasted abilities.
Modern chivalry is about equal strength and ability. In years gone by, women have been equalised within a few margins of perfectly equal with men. There are still some kinks to be worked out in the fine print, and I've noticed that some men even harbor the far gone idea that their women needs to be taken care of like a sick child. There are still places where the other can show their appriciation for their date, but it's not like it used to be.
Without hearing the other side to the date story, I can only offer the initial observation that the guy didn't sound to terrably interested, or perhaps under experianced at dating or perhaps human interest. Perhaps poor upbringing, or listening to "to much of that damn rap music."
This is just a different age. To expect that anything from the previous age to carry over is asking a bit much.
