Haha very funny... but many new flats have these on every room even bedrooms, and most people cut the chains off. Job done. Most people have smoke alarms anyway.
It might make a tiny bit of sense keeping the kitchen and front door closer on but the rest of them are unneccesary, why would you...
Say your kitchen door, you like it closed however when you have to go in you need to push a handle down? Thats hard when you dont have any hands free. Just want to push the door?
Or is the loud 'click' that you get when you close the door annoying?
I found a way to stop this from happening...
