Lewis Hamilton's plans for a night out at a bowling alley with his mechanics were skittled after the McLaren driver discovered they had already agreed to go running with team mate Jenson Button.
The 2008 Formula One champion told British reporters at the Korean Grand Prix that he had also still not spoken to former boss and mentor Ron Dennis since the decision to move to Mercedes next season.
The move, as a replacement for seven times champion Michael Schumacher, was announced on September 28.
Hamilton, who lives in Monaco and has been away from Europe since last month's Singapore Grand Prix, had wanted to treat his mechanics at last weekend's Japanese Grand Prix and also explain why he was leaving.
"I booked 16 lanes at the bowling alley for Saturday night, but something else came up so the guys weren't able to do it," said the 27-year-old. "They were already committed before. They went for a run with JB or something like that."
Button is a keen triathlete and along with many others in the paddock is a regular participant in a charity track run on Saturday evenings at race weekends.
