It means he billed two hours at $90 per hour for a 15-minute session and didn't resolve the problem. I used to work in that field. Billable hours is the greatest game in the workiverse. I left that field because it is totally dishonest work. My work ethic prevents me from charging someone hours of work for something that took 10 minutes to resolve, or not resolve. (No disparagement on you oracle. If that is your thing, then roll with it. It's a great gig.)
That's one reason why I am not rich.
As for the factory manager looking for welders and whining about not finding anyone? Has he ever heard of OJT? Another MORON. He's losing thousands of dollars a day by not having skilled workers. Well, just bring in the unskilled workers, train them, and you get your money back!
MORONS!
I did resolve the problem, I paid $ 19 for software that can break Windows 10 passwords. And no, the company gets $ 180 I subcontract for far less.
