This did make me smile. First the motocy rider charging a falang a total of 450 baht for that journey, outrageous. But the falang decided to spin a dice of his own and scam the scammer, which may or may not have worked. In this instance the falang outwitted the motocy rider.
If the motocy rider had asked for a reasonable sum to begin with I would have sympathised with his loss, but he was just plain greedy himself.
