Petrol Bunk

All three of them slowly entered the shop. There was no one inside. Mark looked around, holding the gun in his hand. As he looked around he found spare tires, different types of engine oils, and repair kits for fixing things up. He thought to keep some spare tires when he would leave this place tomorrow. 

David and Suzie were right behind as he slowly searched for the door for the house behind. Suzie suddenly tugged Mark's shirt and whispered, "There." pointing towards one of the corners of the room behind the cash counter. 

Mark looked and found it was a door. He nodded and slowly went towards the counter. There were no zombies behind it. He quickly went to the door and found it was locked. He then smashed the lock with the gun and opened the door.
