Cyril and Marg Knot-Butter. #gluonguests Owners of a B&B in a rundown seaside town, the Knot-Butter's decided it's time to have a break of their own. Marg expects the best but her ever suffering husband tries to keep his hands firmly on the purse springs and when he decides to treat his wife to a weekend away, he doesn't bother to check the ratings for the hotel he books. He thinks he's grabbed a bargain!
