The Prince and Princess of Wales ventured into London's Soho yesterday, arriving by Tube to enjoy a lunchtime pint.
Prince William and Kate caught the Elizabeth line before attending the engagement at the Dog and Duck pub ahead of the Coronation of King Charles III.
People had lined the streets of Frith Street in London to see the royal couple, with barriers separating them – but it seemed one person managed to bypass security – and it didn't go unnoticed.
In a now-viral video, Kate and William can be seen talking outside the Soho pub before heading in to learn how to pour a pint.
While Kate and William are busy talking, a Londoner holding a bag from a chemist, is seemingly unaware of everything going on.
The man shuffles straight past the Prince and Princess of Wales, looking confused. He is swiftly followed by a security guard who moves him along.
The crowd can be heard erupting with laughter, while Kate, clearly amused, grins as she realises what's happened.
The video has gone down well on social media too, with many saying it reminds them of a "Mr Bean" situation.
Others admired the man's dedication to picking up his chemist order. One person said: "The way he was like 'look I've just been pharmacy, I want no drama'".
Another said: "It's funny because he is oblivious to what's going on, he's just on a mission. He wants to get from point A to point B."
Others remarked on Kate's reaction, with one person saying: "Kate is gutting herself laughing inside. Her face."
Another said: "Kate had a wee giggle."
Continuing their walkabout, William and Kate then spoke to well-wishers who were lining the streets, many of whom asked how they were feeling about the weekend.
The heir to the throne was asked by a Sky News journalist how he was feeling ahead of the big event, to which he replied: "Good, good thank you, if all goes well, good. Fingers crossed, good weather as well."
The Coronation of King Charles kicks of at 11am at Westminster Abbey tomorrow, where he will be crowned alongside Queen Camilla.
