The Queen has a bath every morning, drawn by her maid while she sips a cup of tea. It's believed that the royals prefer to avoid taking showers, due to their belief that they're for members of the working class.
Leave the table without a fuss. If royals need to use the restroom during a meal, they don't announce their intentions. They simply say, “Excuse me,” and leave it at that.
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.
Kate Middleton and Prince William don't often hold hands or publicly show affection. An unwritten rule saying royals must act professionally could be why they rarely engage in PDA. During rare occasions, the pair's been seen holding hands or touching each other's backs.
She says: "These gestures reflect high levels of affection and attraction, so there might be a practical reason to avoid the hand clasp. "As senior royals at events, the hand clasp might be seen as a clumsy ritual when there are many hands to shake and so many people to greet one at a time."
But apparently there's a sweet and romantic reason that the Cambridges avoid PDA. According to body language expert Darren Stanton, William and Kate's don't feel they have to 'prove' themselves on outings because they know they have a 'deep connection'.

Queens had their own intimate ladies, and the office lapsed under Mary and Elizabeth I. So the last Groom of the Stool in the strict sense was possibly Sir Michael Stanhope, who served Edward VI.
Queen Isabella I of Spain, who funded Columbus' voyage across the ocean, claimed to have only bathed twice in her life.
Queen Elizabeth I, too, reportedly bathed once a month, “whether she needed it or no”. Her successor, James VI and I, bore a great aversion to water and reportedly never bathed.
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.
And, as the head of the Commonwealth found out in 1968, a reigning monarch can sometimes have so many pairs she can lose track of them: a pair of knickers left behind on a private plane by Elizabeth II in the swinging sixties and given to a playboy millionaire were eventually sold on eBay for a whopping $18,000.

Despite not being King and Queen juuuuust yet, Kate and William have a huge staff thanks to their position as senior working royals—though unlike King Charles, their aides are not "men in gray" (the nickname given to the power players pulling the strings at The Firm).
