The man – wearing a suit and carrying a briefcase – appears unsteady on his feet as he tries to make his way down the escalator at Tottenham Court Road tube station.
Bemused commuters try to help him off, but he ignores them and continues to try and walk the wrong way.
After struggling for two minutes as people push past, he is guided away by a helpful commuter who pushes the emergency stop button and points him in the right direction. WATCH VIDEO:
The incident was caught on camera last Friday by Sam Napper, 27, who described the man as a “drunk Japanese businessman”.
Sam, from London, said: “At first I thought he was playing silly buggers with a few of his FX Trader mates but when we saw his dogged stagger and realised he was alone, I knew we were about to witness something truly brilliant.
“One by one, concerned commuters tried to steer him in the right direction, to no avail.
“After pausing for a few seconds, he turned around and walked out, as if nothing ever happened, saying nothing.”
