Customer: *storms into store* So what are you guys doing about the problem with the Macbook Pro?
Me: What problem?
Customer: *Rolling eyes* The overheating problem. It's all over the internet, everyone's having it. Don't act like you don't know about it.
Me: We see dozens of those machines in here every week, and this is the first I've heard of it.
Customer: Well you should check out the Apple Customer Service boards. There's a post in there with hundreds of people complaining...
Me: *long, drawn out sigh*
Me: Did you buy the machine here?
Customer: No, I bought it from a mail order catalog.
Me: It's normal for machines like this to get warm when you're pushing the CPU and GPU hard.
Customer: Young man, I've been using Apple laptops since before you were born (note: false), and nothing has ever been like this one. It's a fire hazard!
Me: Would you like to leave it here so that we can confirm it's overheating and replace any faulty parts under warranty?
Customer: No, I want a new computer.
Me: Have you contacted the business you actually bought this computer from?
Customer: Yes, they won't replace it.
Me: As an Apple Authorized Service Provider, we're bound by Apple's company policy with regards to making warranty repairs, which this doesn't fall under.
Customer: So just replace it with a new one.
Me: Sir, you didn't even buy this from us.
Customer: Well can you at least give me store credit or something for my trouble?
