A recent report claims that Queen Elizabeth II and the royal family share one thing in common when it comes to the thing they don't like. An author revealed the family has a secret code, and no one would notice about it.

Queen Elizabeth and other key members of the royal family, like her husband Prince Philip and her son Prince Charles, don't like one particular thing. To get them out in a situation, they reportedly have a secret code, and no one notices their subtle actions.

In his book Not In Front Of The Corgis, author Bryan Hoey revealed the royal family does not like it when their guests stay too long. He claims that they hate it when their visitors overstay their welcome, as they are punctual in arriving and will leave immediately when it's time for them to go.

When their guests don't leave immediately, as per the author, Queen Elizabeth and the royal family have a way on how to get out on the tricky situation. Hoey said the family had devised codes and they let their servants know when it's time for a guest to leave.

He said they'll usually summon a butler, and they will ask if the car of the guest has arrived. The butler will reportedly disappear for a moment and then will announce that the guest's car is waiting in the drive. From there, the royal family will rise and then bids the visitors farewell, meaning it's time for them to go.

The servants of the royal family are reportedly loyal to them, especially in dealing with their demands. Prince Philip, in particular, reportedly picks the most loyal team although he has a reputation for being "rude" and "overbearing," Hoey claims. But despite this, the Duke of Edinburgh is reportedly loyal to his staff as well.

The author said that Prince Philip's loyalty is second to none and he protects any of his team - from valet to Private Secretary, especially if he thinks and believes they are doing the right thing. Also, when his chauffeur died in 2011, the Duke didn't send a representative. Instead, he broke a tradition by insisting on attending himself.

But then, Queen Elizabeth's husband reportedly has a "very high demands" when it comes to guests at dinner parties. For instance, Hoey said that Prince Philip decides the subject for conversation when he hosts a private dinner.
