A burglar was able to remove a bar's front door lock without any trouble, but when it came to getting inside, he tried repeatedly and failed. That's because he was pulling the entirely unguarded door rather than just pushing it open.

You'd be surprised how just the act of opening a door can be complicated for some people.

Take, for example, a man in Chicago who was caught on surveillance video attempting to break into a bar called The Shambles.

The burglar was able to remove the front door lock, by using his tool, without any trouble, but when it came to getting inside, he tried repeatedly and failed.

The problem wasn’t another undetected lock. It was the fact that he was pulling the entirely unguarded door rather than just pushing it open.

Although it’s a little disturbing especially for the owner of the bar, there is a funny aspect, considering the simple word “push” was posted on the door.

In the end, the would-be burglar never did figure out how to open the door and took off. The bungled break in occurred during the early morning hours of a recent Friday.

Earlier on the same morning, another neighboring bar owner discovered his door had also been damaged. It’s currently suspected the same suspect is behind that attempt and unsuccessfully used vice grips to try and pry the locks off.
