Post your BEST customer service experiences

So we always hear about the nightmares, but what are some of the best experiences you've had with a company's customer service department. I've got two:

1. My mom recently started chemo (effing cancer), and before she started she wanted to get these warm boots because someone told her that the hospital was very cool and her feet get cold easily. I've always told her about Zappos but she never did it cause she's old-school about buying shoes in-person.

Anyways, she found this pair she liked and before she ordered she called the customer service place to make sure they would be delivered the next day as the website said. When the lady said they would, my mom (who's a very talkative person) made some remark like "wow that is incredible, I have my chemo starting the day after tomorrow and I never thought they would get here in time, but now I get to wear them during my chemo to keep my feet warm, blah blah blah".

Well,she hangs-up all excited about her boots, and when the package arrives the next day, in addition to the boots they'd included this very comfortable, warm, heavy blanket with a note about staying warm and beating cancer. It made my mom's month. She's basically a pseudo-spokesperson for them nowadays, tells that story to people she barely even knows .

2. I fly regularly on one major airport (basically once a week in and out of the same hub). The other week I realized I forgot the book I was reading in the seat pocket and didn't notice until I got home. I basically assumed it was gone for good, but when I got to the lounge today, upon checking in, the supervisor of the lounge came by and asked if the book was mine. I was stunned and he said they found it, looked up the seat it was in, saw I was a regular flier out of that hub and knew I'd be in the lounge soon so they held onto it. It was an awesome surprise.

Any other good ones?
