One worker at Buckingham Palace found out first hand what it’s like to get the royal treatment.

A builder who was refurbishing a desk at the legendary residence had a bizarre encounter, when he paused to order a spot of tea and suddenly realized Queen Elizabeth had delivered the drink herself, according to an upcoming documentary called “Secrets of the Royal Palaces,” The Sun reported.

The contractor was working beneath the desk in one of the palace’s private rooms, when a voice called out asking if he’d like some tea, ex-royal upholsterer Kevin Andrews, who knew the worker, told the show.

“Yeah, in a mug. Two sugars. Builders’ tea. I don’t want any of that nonsense I had the last time I was here, all that fine china and all that saucer stuff,” the worker said.

The woman who took his order returned a few minutes later.

“I’ve put your tea on the table,” she said.

The man looked up from underneath the desk and saw the Queen’s outline as she left him to continue his work.

The first episode of the documentary series, which focuses on Buckingham Palace, is set to air in Britain later this month, Hello Magazine reported.
