"I asked him what kind of drink he wants later on in the bar," Federer joked. "No. I said, I think the ball is out, really. Anyway, I hope so. He goes, if it is out, I wish you all the best. Please keep on winning and stuff. It's like, Okay, we'll see. Wait for the call first, you know. But he was very nice. He was very supportive of me going on and playing very well in the next few rounds. He seems like a very nice guy. I've played him once in doubles in Davis Cup. He comes across as a very open and kind of cool guy. So it was kind of an unconventional finish, but he was a very nice guy at the net."
