He told me he’d never been so scared in his life, but he had to do something because he had his wife and four little kids sleeping inside the caravan, and so he grabbed his butchers knife (he was a butcher by profession, lord knows why he had it on a family camping trip), opened the door to confront or yell or do whatever he could to scare the people away, but when he opened the door he saw no one and heard no noise. He thought he was going crazy, but he saw the cigarette butt on the ground outside the door, freshly finished. He got into the car straight away (he had everything ready to go luckily cos he’d already planned on beginning driving early the next morning anyways), and drove everyone away and found somewhere else near a town to stay instead.
