Sometimes people go too far on their last day at work. A tour firm in San Francisco has had to issue a public apology after a last day, racist, expletive-filled rant by a tour guide against Chinatown.

This act was caught on camera and is now on YouTube, which now has nearly 1 million views. Be warned the language is quite bad. “On behalf of City Sightseeing San Francisco, I deeply apologize to the residents of Chinatown and San Francisco for the conduct of a former employee,” said City Sightseeing CEO Christian Watts. “Due to this unfortunate incident, we have added additional training processes to ensure that each tour is up to our rigorous standard.”
