請勿靠近車門 is the standard Cantonese warning played on Hong Kong's MTR network before train doors close, telling passengers to stand clear. Commuters hear it dozens of times a day, which made it ripe for meme treatment among Cantonese-speaking netizens, who lift it into edits about crowded trains, personal space and everyday annoyances. Its deadpan automated delivery is the joke: a polite robotic voice scolding you for standing too close. With only two plays and a single like, this upload is a niche find, but the announcement itself is one of Hong Kong's most recognisable transit sounds.
