I've never been asked for one either, but that voltage while at idle is quite low.

That said, with the amount of load placed on the electrical system by the large radiator fan running continuously with the A/C and the internal blower system (along with everything else) it's possible the alternator just can't keep up with demand at the relatively low rotational speed of running at idle.
