Today, a student attempted to walk out of the library with a book cart. No explanation, no asking "Hey, I've got a ton of books, can I take this?" (answer: no, but at least you asked!). This in full view of the library assistant on desk duty. Assistant stopped him and told him he can't just walk off with a book cart. Student was indignant and insisted that he NEEDED it. I was enlisted to explain to the student that the cart is library property, we have no way of knowing where it's gone if it leaves the library, and yes, I know you say you'll bring it back but I don't know you from Adam and there is no way I'm letting you wander off with our stuff.
Student pouted and whined about how was he supposed to get all the heavy, heavy books he'd checked out home? I suggested that he take some of our free bags (nice, reusable bags) to carry them, or in future not check out more books than he can reasonably carry. Student whined some more, I explained that walking out the door with non-checked-out library property was stealing. Student was indignant, but finally left, grumbling about our unreasonable policies.
