The public didn't like Charles and Camilla's first bout of PDA either

King Charles III and Camilla, Queen Consort, played the long game in their relationship. It wasn't until 2001, over 30 years after they first met, that the duo made a public display of affection. 

While at a charity event at the London Somerset House, Charles kissed Camilla, and it got the public talking. At the time, the public was becoming more accepting of Charles and Camilla's relationship, and those in favor were pleased to see the two kissing. 

However, others were staunchly against it, finding the kiss inappropriate for a senior member of the royal family.

While PDA among members of the royal family is certainly rare, it's not technically against any royal rule. As royal etiquette expert Myka Meier told People, "Senior members of the royal family would likely not be told how to interact or when they can or can not show PDA and would be trusted to use their better judgment as to when it's appropriate." 

Meier added, "The royals often adjust PDA to mirror the formality of the event they are attending. At a somber or more formal event, we are less likely to see PDA than at a casual event where it would be deemed more fitting." 

Though Charles and Camilla's kiss was unexpected, they likely weren't reprimanded for it.
