I bet Creepy didn't really reply to the woman who called him a stalker, he probably crawled back into the restaurant with his tail between his legs, scared that someone called him out as the weirdo he is.
You'd have thought with their £10k a day they could have got two caravans so they weren't all on top of each other and the girls could have their own space. It might help Isabelle feel more grown up and that it's more like a girlie trip rather than her being under the control of Lazy and Creepy all the time.
