I am what some might refer to as a "mental midget." I can see you nodding already, but I'm going to explain anyway.
I lost the power cord for my MacBook.
Since I can't even wipe my ass without said MacBook, it was an itchy, irritating problem. This Apple Store was the wonderfully quick solution. I walked in. Some guy asked me what I needed, found it for me, sold it to me, and sent me on my way. Two minutes, tops. And my receipt was e-mailed to me as I was walking out the door.

So now I had two, and I was out $80. I figured I'd drop by the Apple Store to see if I could return the extra. I walked in. Some guy asked me what I needed, took my e-mail address and the extra charger, and sent me on my way. One minute, tops. And my refund for the full price was e-mailed to me as I was walking out the door.
Now that I think about it, I essentially borrowed a power cord from the Shadyside Apple Store for a couple days, at no charge. If I had friends, I would want them to be this reliable, friendly, and easy to deal with.
