That is the letter of the law. In practical use, many pharmacies probably don't do this. Maybe in high crime areas they do, but in smaller towns, or mom and pop pharms, I'd bet they don't.
Just like nurses are supposed to lock the med cart as they run in to offer meds to patients. In reality that doesn't happen if no one is around. What is practicle is often the rule and not the exception.
