I was once on a dark road close to a major tourist hotspot and a tuk tuk driver was pestering a farang tourist.
I was stood near the bakers oven having a beer, it was just those 2 on this dark road when all of a sudden the farang started laying into this tuk tuk driver.
He didnt fight back at all and came back into the area that had street lights and he was crying, blood streaming from his nose.
the farang disappeared into the shadows, never to be seen again.
It was so satisfying to see. I hope he learned the lesson that not all farangs are soft pushovers.
