If I were to leave something in a locked building I'd take the logical first step and see if I can call maintenance or somebody to unlock the building for me. If that wouldn't work I'd weigh my options and see if I absolutely need it at that moment. If I do not need it I'll wait until the building is unlocked, but if it is extremely important I'll chastise myself for forgetting such an important item and then debate if it's important enough to break into the building for it, ultimately deciding I'm tired and head home and hope that whatever the item was for, I can explain what happened.
I never read it but using common sense in stores only employees is allowed to hand out edible substances, why because its a precation so they dont sue the store if they get sick
