The photo, which was a screenshot from Sky News, shows people running from the bridge, including a man caught who is carefully keeping hold of his beer.
People are relating to the image, as a quaint bit of normality on an otherwise awful day.
Howard Mannella shared the photo on Twitter, saying: “People fleeing # London Bridge but the bloke on the right isn’t spilling a drop. God Bless the Brits!”
