No matter who you are or where you live, chances are your parents expect you to fix their computer for free.

It's as if the only reason you're even alive is because your parents were too cheap to pay for tech support.

Which is understandable, considering the kind of mistreatment they subject their computer to on a daily basis would no doubt cost more to fix than a new computer would cost to buy.

Well, being forced to be at her dad's beck and call since practically birth, one fed-up offspring has finally decided to do what most of us only dreamed of doing: She invoiced her father for services rendered.

Okay, so the invoice might have been sent from a billing department run by a suit-wearing beagle.

And the amount due is just one dinner at a Round Table pizzeria.

But the aggrieved — an honest-to-goodness tech support employee identified only as "your awesome daughter" — still managed to get a good dig in under the radar.

Concerning the labeling of her dad as "customer ID 9," she explains:

When I was younger I made up a road trip game and rule number 9 was "if dad doesn't understand, just ignore it". We still claim #9 for random nothings.
