Tourists touching down at Heathrow Airport are being introduced to British etiquette by a video starring comedian Stephen Fry.
Tips which feature in the short film include cheering when drinking glasses are accidentally smashed in a pub, navigating the awkward "after you" loop and mastering the "agreement rule" when a stranger comments on the weather.
Fry collaborated with Graham Linehan - who won a scriptwriting Bafta for The IT Crowd - to make the three-minute video.
