"Toilet" If you're looking for a restroom in Buckingham Palace, ask for the loo or the lavatory.
Instead of toilet, they'd refer to that particular room as the lavatory or loo.
And it turns out the royals can't even quietly pop to the loo without remembering to do a few things. A royal must never 'announce their intentions' when they leave the table to go to the loo. Instead they must just say "excuse me" and leave.
The monarch isn't a fan of a deep bath either, she is said to bathe in “no more than seven inches of water”, according to royal author Brian Hoey for the Daily Mail. Seven inches is equivalent to 17.8 centimetres.
Fans of The Crown with a keen eye for detail will have noticed that when King Charles, then known as Prince of Wales, has a brush with death following an avalanche on a ski resort, his handlers use the term 'Operation Menai Bridge' to signal his presumed death.
Perhaps the most oft-transgressed maxim is touching a member of the royal family in a manner that goes beyond a formal handshake—a guideline that likely dates back to the Middle Ages, when, as the British historian Kate Williams has noted, “monarchs were divinely appointed to rule by God, so they were kind of seen as ...
Apparently, she heads to bed at 10.30pm each evening in order to get a good night's sleep. The bling is stunning, obviously. Regular exercise is also said to help with sleep and Kate leads an active lifestyle, often talking about how she loves to get outdoors – it's thought that she runs or walks every day.
No washing machines
Prince Charles and Duchess Camilla's clothes are not allowed to be cleaned in washing machines—everything is hand washed. When they sent their clothing away to be cleaned, they found that some items of clothing were kept as souvenirs.
As an old tradition dictates, royal couples never share the same bed or bedroom, allowing them to move freely while asleep. It allows them much needed alone time after hours of being in the limelight.
They slept in separate beds
As etiquette expert Lady Pam and Her Majesty's cousin explained in a biography about her relative: "In England, the upper class always have had separate bedrooms. You don't want to be bothered with snoring or someone flinging a leg around.
Royal women like Meghan and Kate often keep things casual at official events, wearing affordable brands and easy-to-wear styles, and that includes blue jeans. Here, 20 times royals have worn denim, from Prince Philip and Princess Alexandra in the 1950s to Meghan and Kate today. The Queen isn't one to wear denim.
Why do the royals sleep in separate beds? Reportedly, the reason why some royals chose to sleep in different beds all comes down to an upper-class tradition which originated in Britain. According to Lady Pamela Hicks, Prince Philip's cousin, the aristocracy "always have separate bedrooms".
Water Closet (WC)
Blame this word's French origin for why it's banned in royal circles. If you're looking for a restroom in Buckingham Palace, ask for the loo or the lavatory.
Royal Moms Don't Have Baby Showers
Royal babies go through diapers just as fast as regular babies, after all.
The only time the Queen was photographed in pants was during the Royal Tour of Canada in 1970, when a young tailor crafted her a matte-silk trouser suit in an effort to update her look. Apparently it never stuck, and the moment has become the only time the royal wore trousers in public.
And as to putting one's clothes on, contrary to popular belief the Queen actually dressed alone. The monarch also did her own make-up for most events, with the exception of her annual Christmas speech, for which a make-up artist was employed.
The Queen preferred grilled fish or chicken, served simply with vegetables. She generally skipped starches like potatoes, grains, or rice during her evening meal.
Simple cooked meat and vegetables lead the way, with space for pheasant or venison should the Queen wish. Of course, Queen Elizabeth loved a Sunday roast just as much as anyone else. Along with chocolate, the Queen enjoyed some strawberries or peaches for dessert.
Queen Elizabeth adhered to a daily teatime meal; her preference for delicate sandwiches with the crusts cut off was well-publicized. Her favorite version was reported to be smoked salmon with cream cheese. If the old adage is true, one should eat breakfast like a king, lunch like a prince, and dine like a pauper.
These include chocolate, coffee, and garlic — all ingredients that can destroy your breath. Charles' wife confirmed this during an episode of "MasterChef Australia." Camilla Parker Bowles said garlic was the one food she wouldn't want to see at a royal reception, due to Charles' distaste for it (via Twitter).
Mr McGrady worked at Buckingham Palace as a royal chef from 1982 to 1993, and he told The Telegraph: “No potatoes, rice or pasta for dinner.” The Queen is reportedly not a fan of carbohydrates, so they are never present at the dinner table for any members of the Royal Family.
Women who have famously refused to curtsy to the Royal Family include Cherie Blair, when husband Tony Blair was Prime Minister.
