It was the same on the royal yacht Britannia, I was told by a former member of the ship's crew. They were Royal Navy and served their commanding officer and the Queen.
It was very difficult for them when one of the known arseholes in the RF started throwing his weight around, being rude and vile, having temper tantrums and generally treating the crew like shit. They, the crew, were supposed to just put up with it.
In terms of Dior, would the company require 'full disclosure' from Meghan before a legal deal was signed? It's pretty common for people approaching a new role to be asked, 'is there anything in your background that would embarrass you or us if it came out?' If I were hiring or signing up celebs like Meghan and Harry * , who have already publicly indicated a certain lifestyle, I would want to know about any secret reports and drug use any other hostages to fortune.
*MailOnline is suggesting today that someone claims that Dior may sign both H&M. Yeah, I know, tenuous. But it was pretty obvious yesterday the Mail's up to something with this 'developing narrative'.
