Actually, didn't H write about stealing ornaments from his grandmother and giving these out as presents?
So wouldn't the staff now be liable for the UK equivalent of possession of stolen property? And even if asked the staff are now put in the position of either taking the blame or accusing the monarch's grandson of common theft.
All because H was too cheap to reach into his pocket at get proper presents for the staff who worked so hard to manufacture H's "cheeky happy chappy" image!
