A useful message?

I’d a big day ahead of me. I’d done all my preparation. I’d rehearsed the presentation, and prepared the room the night before. On the early train to London, I’d looked over my notes one last time, and visualised how things would pan out. What could go wrong?

Arriving in the conference room, I checked the room was as I’d left it the night before. It was. So I got myself a strong coffee and turned on the projector, only for the following to display on the screen.

“The bulb is coming towards the end of its useful life.”

As user assistance goes, it tells you exactly what you need to know, but it’s not what you need to see at 7:45am when you’re expecting a room full of people in little under an hour’s time!
