+ 0 Votes my two cents in additon to seanferd's PurpleSkys Moderator 3 years ago We used to smoke. Fortunately, we do all our own computer work but I'll be honest, have you ever seen the inside of a machine that belongs to a smoker? Ewwwwww....it's quite icky to look at. Everything is all black from the tar and chemicals from the cigarettes...and no, I didn't sit on top of my computer either and **** smoke into it. Smoke lays in the air and it doesn't take much for it to get sucked into a pc and then get all clogged up with the smoke and residue that comes from smoking. So yes, computer companies are well within their rights to refuse to work on computers that come from a smoker's environment. They are a hazzard to the tech's health.
