Exactly, for instance, if you were a highschool principal, overseeing a science department with a storeroom full of acids, explosive reagents etc, would you rather call a locksmith to drill and replace a lock the next morning, or explain to horrified parents that it's not your fault that their kid-cum-chemist has nicked reagents and put himself in hospital?
Of course, if it was an environment like a school where the lock was likely to be regularly messed with, you'd want to put a padlocked sheath over the door lock so you weren't constantly having to replace expensive locks, and for a highschool something like an Abloy would probably be sufficient anyway, but you get the point.
