“I was waiting with my patient for an ambulance to transfer him to hospital and although I was keeping him warm it was very cold outside,” she explained.
“All of a sudden, I looked up and saw someone who looked like David Beckham walking past us. He said hello and got in his car. I said to the man I was treating, 'I think that was David Beckham'. Ten minutes later, he came back with a cup of coffee for me and a tea for the patient.
“We were both very amused, and flattered. It was awful cycling around in the cold and I couldn't believe it when he came back with some hot drinks - I was so chuffed.”
Beckham stopped to pose for a picture with Ms Maynard and it was later tweeted by the London Ambulance Service (LAS) with the hashtag #buyitlikebeckham.
The LAS added that Beckham had shown he "respects the service's hard-working paramedics and even a gesture as small as buying a cup of coffee makes our crews feel appreciated".
Beckham’s kind gesture comes a year after Ms Maynard was assaulted by two separate patients within two days.
“I'd only been assaulted once in five years and then I'm assaulted twice in one weekend. It's frustrating that we are sympathetic to so many people, and then we're treated like this,” she said.
Earlier this month, Beckham was been honoured by UNICEF for his humanitarian work for children.
Meanwhile, H&M has just released pictures of its latest collaboration with Beckham.
