Oh, plans. Right, and then half of the shops put a (real steel) chain and padlock (or a large piece of furniture) on the emergency exit, or they use the exit stairway as storage. But indeed on the plans there is an emergency exit anyone can open if needed.
Not in the US they don't. Emergency exits frequently have alarms but locking those doors is a good way to get your business shut down. (Yes violations do happen, but those businesses get fined and shut down pretty quickly.)
