Mr Roberts believed that his wizarding guests were confused with Muggle money because they were all from out of the country; one even tried to pay him with a galleon. Ministry of Magic employees were required to perform Memory Charms on him several times a day.
When Arthur Weasley and his party were leaving the campsite the following morning, Mr Roberts wished them a Merry Christmas, although it was the middle of summer. Mr Weasley explained that Mr Roberts had been left temporarily disoriented by the Memory Charm that had been used to erase his memories of the Death Eater attack.
Behind the scenes
- The Robertses did not make it to the final cut of the film adaptation of Harry Potter and the Goblet of Fire. A brief shot of them being tortured by Death Eaters during the Quidditch World Cup riot can be seen, however, in the film's official trailer.
