One of the cardinal rules of being British is to stand on the right-hand side of escalators when using the London underground, to allow those in a rush to walk on the left.
But in an attempt to cut queues at Holborn tube station, Transport for London has taken a controversial step: It's allowing commuters to stand on both the left- and right-hand sides of escalators.
TfL says the trial will only be enforced during morning peak hours, not evening peak hours, at the busy station, which is used by more than 56 million passengers every year.
A TfL spokesperson told BuzzFeed News: "It's a very crowded station in the morning, people are even queuing from platform level. The trial aims to reduce that congestion."
She said that as the escalator at Holborn station is "very big" – 23.4 metres long – most people prefer to stand because they "can't be bothered" to walk up the left-hand side.
On Thursday morning, several people passing through Holborn station told BuzzFeed News they'd refuse to abide by TfL's plan.
"It's a bad idea," Vicky told BuzzFeed as she rushed off to work at Holborn. "If people want to dawdle, they can stand on the right. I won't be standing on the left."
She was not alone: A number of other commuters said they would be very upset at the prospect of people standing on the left-hand side, and some even said they would try to push past those standing.
Shalah said defiantly: "I won't stand on the left. What if people are in a rush? How will they get through? Most tourists don't know to walk on the left anyway."
John shared his thoughts on the new scheme with BuzzFeed: "It's a stupid idea."
