Every Londoner knows the golden rule of the escalator: walk on the left, stand on the right.
So when transport chiefs tried to introduce a new system at one Underground station, commuters simply weren’t having any of it.
The new six-month trial, taking place at Holborn station, is trying to force travellers to stand on both sides of two of the upward-travelling escalators in order to boost capacity.
A previous three-week trial at the same station saw a 30% increase in people using the escalator at peak time, as well as a reduction in the need to close the station due to overcrowding, the Evening Standard reported.
But despite the improvements, commuters really were not happy with the new system…
Some people took things a step further and went with full-blown civil disobedience…
And there's this poor bloke who had to enforce the whole thing...
When the trial was announced, Peter McNaught, operations director at London Underground, said: 'It may not seem right that you can go quicker by standing still, but our experiments at Holborn have proved that it can be true.
"This new pilot will help us find out if we can influence customers to stand on both sides in the long term, using just signage and information.
'Anyone who wants to walk on the other escalators will be free to do so, but we hope that with record numbers using the Tube, customers will enjoy being part of this experiment to find the most efficient ways of getting around.'
