Ragnar was about to leave if it wasn't for the money being offered for such an easy job. The job was to apparently go break down the man's door while he was at work before spray painting his house with a message and then leaving after trashing the place.
Well this was easy enough as Ragnar left with the paint can and walked over to the man's apartment building, this was the middle of the day so it was wasn't like Ragnar wasn't going to get seen but I think that was kinda the point of this as he walked to the mans door and without any real effort kicked in completely into the apartment, off the hinges.
