So this Senior Programmer is printing a 180-page report on 6-page-a-minute printer (* now you have a clue how long ago this was *), and I was waiting for my turn at the printer.
Him: "Don't bother waiting. This report's all wrong. I can't kill the print job because my PC's locked up, but I'll have to start over when it's done printing."
Me: "You want to kill the print job? But the system isn't letting you? And your PC's locked up so you're going to have to reboot anyway?"
Him: "Yeah, we'll just have to wait. Unless you have a better idea."
I turned the power switch Off.
Him: "Waaah! What are you doing? Don't do that! They told us never turn the power off!"
Me: "And why would that be?"
Him (patiently explaining to the junior staff): "If you turn the printer off, the current job is lost."
