Random acts of Mac kindness

I was shopping in a large box electronics store yesterday afternoon (let's call it "Wiring Town:), when I happened to overhear a woman and her daughter ask a salesman about which camcorders would work best with her "Apple." After fumbling around for a few seconds, he admitted he didn't really know, but finally concluded that she'd probably be best off with one that writes to mini recordable DVDs. I just couldn't help myself, so I waited for him to wander off and then approached her. I told her that he'd given her terrible advice and that she really should go home, get online and do some research. She thanked me and I then excused myself; as I was walking away I heard her chuckle amusedly to her daughter about what zealots "Apple people" are. Now, of course, I'm a big time Apple blogger and all (yeah right), but I couldn't help but wonder: what other company could inspire perfect strangers to do its bidding the way Apple does? So, dear TUAW readers, do you perform random acts of Mac kindness? Do you have any good stories? Please share them in the comments.
