Taxi drivers and the mentally insane

I swear to god, to be a taxi driver in Asia you pretty much have to have just been released from a mental institution. You need to look as though you are a mentally sound person but secretly you are one step away from a serial killer. Dress as though you would imagine any regular person and be well groomed. Be fluent in hand gestures and a little English to be able to agree on a price and look as though you are satisfied with the deal.
After all passengers are arranged in the vehicle proceed to drive the length, breadth and width of the country. All whilst the meter is on, even though you had previously agreed to a price. When passengers kick up a stink because they realize you are taking them arse about town, scream at the top of your lungs, NO, NO, NO! This is where you should start twitching like a maniac and becoming slightly aggressive.
Finally when you reach the destination and passengers only pay the agreed price, get out of the taxi and yell like previously mentioned. If this has no result try to grab the smallest person there (Steph) in the hope that physical aggression will scare the crappers out of passengers and they will front up some more cash. But
be aware there possibly may be people who are more than likely to be just as aggressive back (Me). In the end you have to learn to just give up like a spoilt kid and get back in your taxi, pout and try to rip off the next tourist.
Luckily we were also traveling with the Dutch couple we met in Ha Long Bay. They were 3 times taller than Steph and I and they were able to handle the situation. Otherwise I may have exploded by this stage...I may be close to a little episode of a mild aggressive outburst soon if I come across anymore crazy Asian behavior
