Jamie Murray is getting used to mingling with royalty

Jamie Murray found himself a familiar presence at Buckingham Palace a few weeks ago. The fourth-ranked doubles specialist went there for a state reception, and was also invited to the royal residence to receive an OBE from the Queen.

"Twice in a week," the older Murray told reporters at the ATP Tour Finals in London. "I didn't really expect it at all. [I] felt really honored to receive that."

Murray, whose wife is from Colombia, was also invited to a state banquet for Juan Manuel Santos, the president of Colombia.

"Yeah, I mean, such a unique thing to go to," said Murray.

The 30-year-old said that other guests were aware of his chase to be the No. 1-ranked doubles player, and knew of his younger brother Andy's pursuit of the No. 1 singles ranking.

"We had a really nice night, met a lot of nice people,” he said. “They were all kind of rooting for us to try to finish at No. 1. They were kind of on top of what we were doing. Prince Charles—he was, yeah. The Queen, I laughed because she said to the Colombian president—when I met him—she's like, 'I've seen him play tennis before,' which I thought was quite funny.”

He also admitted that he wasn’t familiar with the food etiquette, as well as other customs.

"They bring it around and you take it off the plate," he said. "I just assumed it was, like, one piece for each person ... You know, couples, they don't sit next to each other. At the end of the meal, I went to my wife [and] said, ‘I think I'm going to need to get some more food.’ ... The two guys she was sitting next to were, like, piling it in. They were a bit more experienced, I think."

Murray is a two-time Grand Slam doubles champion.
