Interim manager Rafael Benitez attempted to alleviate boredom during the Blues' Club World Cup trip to Japan - and distract his squad from their lingering jet lag - with a visit to a local bowling alley in Yokohama.
Almost inevitably, the games became highly competitive, resulting in full-back Cole waiting on a handful of his team-mates back at their hotel.
Cahill said: "We went out and had a bit of a team bonding, bowling, to see the area and the people. So that was good.
"It wasn't about who won, it was about who lost in our group, because whoever lost had to get the dinner in. It was Ashley Cole.
"He's a better left-back than a waiter.
"The only tip was, 'Don't do it again'."
Cahill added of the bowling trip: "I think we took up the whole place. Everyone played, the manager, staff, everyone."
Insisting he did not notice Benitez's score, Cahill said of his own performance: "I was average. That is how I describe myself as a bowler."
And the others?
"There were a few strikes," he added.
"The standard was all right, actually. It was quite good.
"That was the only day that we actually had out. We're not here on holiday. We're here for a reason.
"But we've had a bit of down time when we first came and it was good to get out for an hour instead of going stir crazy in the hotel."
It is rare for top-flight players to be away from home long enough during the season to engage in such team bonding.
"It is hard because you have got so many games," said Cahill, who has embraced the trip to Japan.
"They've treated us nicely," he said of the Club World Cup hosts.
"The food's very different. We've got our in-house person overlooking the food but it's been half the old pasta and chicken and half the Japanese style.
"So we have eaten some Japanese food. We ate in the hotel last night, which was Japanese."
Chelsea's bowling trip was not the only squad outing in recent weeks, with former team-mate Didier Drogba last week arranging a dinner in London for their Champions League-winning squad.
Drogba presented each player with a specially-made ring worth a reported £80,000 each, and Cahill said: "It was an amazing surprise.
"I had no idea when he came in and called us all together.
"I was very touched. It was extremely generous for a start because it was his idea and no-one needs to go out and do that - not just for us, for the staff as well.
"It shows what his character is - he is a great lad.
"It reminds us of what a great achievement it was. He said that's why he did it, so that none of us forget what a huge achievement it was.
"It's something I'll keep for the rest of my life. It's not a ring I'd wear. I'm not flashy. It's more of a memento.
"It's personal and individual to every player and something you want to save."
