People shouldn’t need an incentive to be polite to one another, but if you need one, here’s the best one we’ve seen in awhile. Recruiter Matt Buckland shared the perfect reason for never saying, “Go f**k yourself” on a train.

Last week, Buckland tweeted that a man who pushed him on the London subway and cursed at him later turned out to be the person he was interviewing that afternoon.

“I was on my way into work on the Tube on Monday morning during rush hour,” Buckland told BBC News. “I stood to one side to let a lady get by, and ended up blocking a man momentarily. He shoved past me, almost knocking me over, and shouted.”

When Buckland got to work at Forward Partners, a company that funds start-up businesses, the day went on as usual. But his 5:30 p.m. interview was a surprise, as it was the man he saw earlier on the train. Initially, the man didn’t recognize Buckland.

“It was totally awkward,” Buckland said. “So I approached it by asking him if he'd had a good commute that morning. We laughed it off and in a very British way I somehow ended up apologising.”

Buckland told the BBC that the man didn’t get the job, not because of the encounter earlier in the day, but because he wasn’t fit for it. The job is still open.

Buckland’s tweet has been retweeeted over 21,800 times and is up to 20,400 favorites.
