Back in college, when I used to work in the computer maintenance group, we would spend the summers upgrading the school’s public labs. It never fails, you can put up big signs saying “cluster closed for maintenance” that all but completely block the entrance. You can shut the doors. You can remove every single computer, cable, and even desk from the room. Yet the numb-nuts still walk in and force you to go through the same exchange:
Me: “I’m sorry, the cluster is closed.”
Them: “Oh. Can I still check my e-mail?”
It being the summer, these were usually grad students. Sometimes professors. :rolleyes:
