You can report them using apples feedback service, they usually send out a "how did we do" email to you after your visit, they did every time for me so far...
I reported a guy who was incredibly snotty to me when I brought my MBP in, he accused me of jamming a screw driver in my CD, then proceeded to completely ignore me and mark the "damage" down as "user caused damage", I filed a complaint about him, when I went in again, I mentioned him to the person serving me, turns out he was fired, he'd received several complaints prior.
So yeah, sometimes, moaning away helps
http://www.apple.com/retail/feedback/ That link might help you, but I think that's more for purchases, rather than support service feedback.
You could always ring Apple if it really bothered you and ask if there's a phone number you can call to lodge a complaint or a weblink they provide.
