People who borrow stuff and never bring it back annoy the crap out of me. We have a cart outside of our office that clearly says "Property of Internal Communications." Anyone is free to use it, just give us the courtesy of letting us know. But it disappeared for a week and was found locked in some random closet. And now, our cooler is gone. Again, just ASK people. Otherwise we're going to have to start bolting things to the floor.
Not sure why, but I blame millennials.
