Every Windows user has seen a blue screen of death at some point in their lives. Turns out Tesco is a Windows user. Their self service checkouts use XP with a piece of software called NCR Fastlane.

I know this because both checkouts simultaneously crapped out at the Tesco Express beneath where I live just now, while I was buying some sausages.

You quite often see BSoDs on the screens they put in the windows at places like HMV to advertise whatever it is the kids listen to nowadays, often with flustered employees next to them trying to work out how to press Ctrl+Alt+Delete when there's no keyboard.

When will they learn? If it matters, don't use bloody Windows. Do air traffic controllers use XP? (I bloody hope not. Still, better that than Vista.)
