What part of "first come, first served" are you having difficulty understanding?

What, your vintage Satellite A75 P4-based boat anchor is burning a hole in you lap? Yeah, we can fix that. You either need to have your cooling system cleaned or your fan replaced. No, we don't do appointments. We operate on a first come, first served basis. You will need to check in your machine and leave it with us. No we  are not going to tear your machine down and clean it out while you wait. This machine has no easy access door for the cooling system. The whole motherboard has to be removed. So yes, you will have to leave your Precious with us if you want it fixed. Sorry.

You could probably do with some unplugged time anyway. It'll be good for you.
