Production of Irn-Bru was reportedly shut down during the Queen's visit to its factory over fears it would be 'too noisy' for the 95-year-old monarch.
Her Majesty officially opened a new production facility for the classic Scottish soft drink in Cumbernauld yesterday.
She was joined at the AG Barr plant by her grandson Prince William, who was seen enjoying a sip of the fizzy beverage.
And according to Sky News correspondent Gerard Tubb, the entire factory was shut down during the visit as "apparently it is too noisy for a 95-year-old to put up with".
He added: "I’m not sure if that came from the factory or if it came from Buckingham Palace.
“But it was all shut down and it will be hours before they get it all back into production again and sending drinks right around the world.”
The Queen's visit to the factory was her first official engagement north of the border in Scotland since the death of her husband the Duke of Edinburgh in April.
She met employees at the factory and was given an overview of the history of the company.
The monarch is in Scotland all this week for Royal Week - where she will take part in a series of engagements.
Today she will be joined by Prince William once again while Princess Anne will accompany her while she is out and about later in the week.
She is staying at the Palace of Holyroodhouse in Edinburgh, her official residence in Scotland.
Royal Week was cancelled last year because of the coronavirus pandemic.
This year, in line with Government guidelines, traditional events hosting thousands of people such as the garden party at the Palace of Holyroodhouse will not take place.
Emphasising the Queen's commitment to Scotland, Buckingham Palace tweeted: "Her Majesty is connected to Scotland by ancestry and deeply held affection.
"As well as spending family Summers at Balmoral Castle, The Queen has visited almost every area of Scotland from the Outer Hebrides to Dumfries, meeting Scots from all walks of life."
