William, Kate, Harry and Meghan and the like attend some seriously fancy gatherings.
And with such fancy gatherings, come a set of important rules that must always be followed, especially if you're a member of the royal family.
Not only do they have to make sure they're holding their cutlery correctly, but they even have to go to the loo in a particular way.
A royal must never 'announce their intentions' when they leave the table to go to the toilet at a dinner party. Instead, they must simply say "excuse me" and leave, according to Business Insider.
If they haven't finished eating their meal when they get up, they must also cross their knife and fork. This means that their staff will not take away their food while they're away.
However, if they have finished their meal when they get up, they must put their cutlery at an angle, with the handles at the bottom right of the plate (essentially 4.20pm on a clock).
So many rules, it's a minefield!
