According to the Bamboo Telegraph
The guy in the red car stopped to let an old person cross the road. The guy following behind got pissed off, blew his horn and decided to overtake the red car, almost running over the old person.
And that's how it started.
In the video the Filipino in the green shirt tells the fatter of the two to go home. Probably deserved.

@PatO I didn't see any fighting skills in that video The best fight so far was the Texan in Dauin thumping the crap out of Mark Higgins and the other wannabe gangstra. LOL

 

This kind of behaviour is the reason foreigners get a bad reputation. The idiot(s) should be strung up!
