Claiming to be an "ex-Parachute Regiment" soldier whose uncle died in the River Kwai during World War II, the tube passenger first threatens a female passenger:
"Get yourself off the train, get yourself off the train. You're nasty people, yeah? F*** off, get out of my country. Sayonara."
The person filming the footage then confronts him, asking: "Does it matter, really? Are you going to start sorting everyone on the train, man, one by one? What have you got against the Japanese?"
To which the passenger responds by waving the wine bottle and saying:
"Do you want some of that? No, because you don't drink. You're a f****** Somalian c***."
The first comment beneath the YouTube video, which you can watch in full below, says it all.
