• A San Francisco bus operator live-tweeted his reaction to the bus fight scene in "Shang-Chi."
• The hilarious Twitter thread, which included his reactions from the perspective of a bus driver, went viral.

A San Francisco bus driver broke down a fight scene in a public bus in Marvel's "Shang-Chi and the Legend of the Ten Rings" in a hilarious viral Twitter thread earlier this week.

On November 13, Mc "Mack" Allen, a bus operator with the San Francisco Municipal Transportation Agency, posted on Twitter to rate the iconic bus fight scene in the Marvel feature, which is now streaming on Disney+.

His Twitter thread of reactions to the scene garnered thousands of likes as he nitpicked details of the scene from the perspective of an SFMTA operator, pointing out how nice the seats of the bus in the movie and that the jazz festival ads on the bus were authentic to real-life.

At the moment that action began to ramp up in the scene when one of the henchmen threw a punch at Shang-Chi (Simu Liu), Allen wrote: "As a bus operator, this is the moment I pop my parking brake and open the doors."

In the scene, supervillain Razor Fist (Florian Munteanu) cuts through an air hose under the bus with his weapon, causing the brakes to fail. The scene cuts to the bus operator (Michael-Anthony Taylor) "mashing on the treadle (pedal) and not stopping," Allen wrote.

Allen added: "And he's wearing earphones. That's terrible. He definitely could be charged with an avoidable incident" by San Francisco Transit, the fictional transportation agency in the movie.

The driver later looks behind his shoulder to see the fight in the back of the bus, which Allen said operators shouldn't do.

"When bus operators want to know what's going on inside our passenger area, we look in the mirror up top, not over our shoulder," he tweeted, adding that the titular superhero made a better example of how operators can check on passengers.

Allen later joked that Shang-Chi hanging from the side of the bus resembled passengers asking to let on: "This is how everyone asks to be let into the bus when we aren't at a stop."

Towards the end of the fight, the superhero told his friend Katy (Awkwafina) that he would signal to her when to make a hard right, separating the passengers from his enemies. Pinned against the window by Razor Fist, Shang-Chi pulls the stop request line, prompting his friend to turn and splitting the bus in half.

Allen said he could see the gag from "miles away," adding that it was hard to believe that none of the other passengers had pulled the line earlier in the chaos.

Allen told the San Francisco Chronicle that his newfound viral fame "is so incredibly entertaining."

"When I turned my phone back on there were hundreds of thousands of views of the tweet, and it's still going," he said.

The viral thread also caught the attention of the film's star, Simu Liu, who plays the titular superhero.

"This is f**king amazing," Liu tweeted in response.
