Hey, guess what? My job is a fucking prison!! They like, have locks on all of the doors and you can't gain entry without an ID & key. And since it's all electronic, that means that they can tell every time i enter the building! WTF happened to freedom?!? I have to wear a photo ID badge at all times!! WTFF!!
But then again, it's a lot harder for some nut job/disgruntled employee to come in and shoot up the place, and it doesn't inconvenience me in any way, shape, or form, so I'm actually a fan.
You should be thankful that your school takes your security seriously. Hopefully it's never needed.
