A San Francisco sightseeing tour bus guide chose to let all of her bilious racism out on her last working day, shouting racist slurs into a microphone as the bus drove through the Chinatown neighbourhood.
One customer caught the rant on camera (albeit with a vertical video when will people learn), though it didn't seem to discourage the guide.
It isn't yet clear which sightseeing tour company the woman works for, but so abhorrent are her words she may take it down with her.
The worst thing about the video - midway through the rant others on the bus actually clap her.
An excerpt from the rant:
"F*ck your pre-schools and your little pre-schoolers making all that noise at six in the morning when I was trying to live here. F*ck your salons, f*ck your little herb gardens, f*ck your little seafood f*cking markets with your turtles and your frogs inside, OK.
"When you come to America you gotta assimilate a little bit, and here in America we don't eat turtles and frogs. They're gonna bring that here to America? There's a limit ok.
"F*ck your laundry hanging out the windows, f*ck your three or four people inside each one of your little SROs, f*ck your noise, f*ck your parades, f*ck your dragons, f*ck this shit, f*ck Chinatown."
