On Christmas Shopping
The final days of the Christmas shopping period bring out Christmas trolls; groups of short, fat beings with unpleasant odours and a constantly agitated look on their face. Christmas trolls cannot walk at a pace faster than 1km/h, and tend to walk in groups of three to five, always side by side, often stopping randomly in walkways to converse about nonsense, clogging the flow of foot traffic and causing annoyance to a great many.
