Long into the evening they were debating the merits of the new Dr Who. Why bother? Roger Federer had long since confirmed he is the real Time Lord.
I know he gets paid a few millions for putting his Rolex back on as soon as he finished playing in time for the TV interviews, but you wonder why he bothers with a watch at all. The seconds, minutes and hours that chip away at the rest of us just don't seem to affect him.
In a year when all the world's top tennis stars were dropping like flies through various injuries and ailments, when his Wimbledon final opponent Marin Cilic was reduced to tears by blisters on his foot, Federer just sailed through serenely.
He'll celebrate his 36th birthday in three weeks time yet was the fittest man at SW19, and hardly surprising because he had to do the least work in winning the title of anybody since Bjorn Borg in 1976, the last man to be crowned champion without losing a set.
The final only took 101 minutes, but I enjoyed every one of them. Having backed him at [8.2] as early as January after his epic Australian Open win over Rafael Nadal, then again at [4.3] when he withdrew from the French Open, it was one of those nice but rare afternoons to sit back and wait to collect your winnings without it ever being in serious doubt.
Federer had always set his heart on this milestone victory, whatever he'd have tried to have you believe. The 19th Grand Slam - so eclipsing Jack Nicklaus from another sport - as well as the eighth Wimbledon title to stand on his own ahead of Pete Sampras.
There was a ruthlessness about it, from the way he skipped Paris to get his fitness preparation right to the way he ignored Cilic's obvious mental and physical pain on Centre Court to just walk into place and send the signal that he was ready to show now mercy.
Now, of course, comes another question. Can the Time Lord continue his travels to collect a 20th Grand Slam when he heads for the US Open in August?
Once matched as high as [19.5] to collect what would be his sixth title at Flushing Meadows, his Wimbledon triumph has seen his odds crash to become the [3.55] favourite. That seems very skinny, but then it's hard to see who offers a genuine threat.
Nadal comes next in the betting at [5.0], with the other members of the Big Four Andy Murray [6.4] and Novak Djokovic [6.2] not far behind. Given their assorted problems with knees, hips and minds however it's hard to think any of them offer value.
Then you have the likes of Cilic [19.5], Stan Wawrinka [14.0] and Milos Raonic [29.0] who could be a threat but don't seem able to put two weeks of consistent tennis together.
Federer himself seems to have little doubt that he can go on defying the years. That effortless backhand, the smooth movement across the court, the textbook service action. It's all designed to put the least amount of strain possible on a body that he keeps supremely supple.
"Can you still be playing and winning titles when you are 40?" he was asked after his latest triumph.
"You would think so, if health permitting and everything is ok," he said.
Seems like the real Time Lord will go on travelling, and he doesn't even need a Tardis.
