Damn right, and well deserved. They gouge tourists and expats with outrageous fares, they flout the law, and a car door that isn't ever so gingerly closed warrants a slashing of a tourist's stomach.
I'd like to see this buffoon taxi driver in prison. A picture should be taken every few months to remind other larcenous taxi drivers.
If you love taxi drivers too much, pay double the fare.
If you don't do that, then stop lauding these louts.
