Alongside his wife Camilla, the Duchess of Cornwall, Charles was chatting to workers at an Asda distribution centre to thank the people who have kept the country's vital food supplies moving throughout the coronavirus pandemic.
But as the unknown man was speaking to the 71-year-old Prince of Wales, he started swaying from side to side before completely losing his balance.
After being given an indication that the man was now in the recovery position and seemed to be coming round, Charles moved on to the next person he was due to chat to although, he did continue to glance over.
In the background of the video, the man can be seen being helped to his feet before he's taken from the marquee.
Thankfully, the man was unharmed and managed to finally continue having his conversation with the royal, albeit with a slight smirk on his face.
LADbible has contacted Asda for a statement.
During the site visit, staff members were standing two metres apart in a marquee outside the firm's main building.
According to the Mirror, employees told their stories of how they'd returned to work from retirement, worked extra hours and postponed holidays in a bid to help with the increased demand that came with the coronavirus lockdown.
Chris Tilly, 48, general manager of the distribution centre, said work had been 'really, really challenging' and paid tribute to staff.
He said: "We've had a lot of support from colleagues right across the business working extra hours, extra shifts to keep the shelves filled for customers."
Richard Sigward, 74, a warehouse operator, has been working for Asda for 17 years and told Charles and Camilla that he refuses to retire.
He explained: "The duchess was saying to me she definitely agrees that if people can work and are happy to do it, they should carry on. She said she refuses to retire herself. The prince was the same."
As their visit came to an end, the royals unveiled a plaque marking the day, with Charles saying: "Thank you, thank you very much everybody. You deserve a stiff drink after all this."
We know one person that definitely did.
