Ulp...
User calls me.
User: My laptop won't turn on.
Me: Are there any lights showing?
User: No, it's just not working.
<We go around the houses a few times checking the power etc>
Me: OK, looks like it'll have to come in.
<Time passes, then user comes into my office>
User: I've brought my laptop in, it still won't turn on.
Me: OK, let's have a look.
<User hands me laptop case, most notable feature of same being a &%$£ing huge tyre-mark across the middle.>
User: It's just not been working at all...
Me: ...since you drove your car over it?
User: <sheepish look> Errrrrr...yes...
Me: No shit.
User: Is it covered under the warranty?
Me: Oddly, no...
