"Hate These Taxis"..only in the Philippines

What's with these Manila taxi's?? The moment the rain starts pouring heavily, and you're trapped in a mall or somewhere, these taxi's that has been going around everywhere, suddenly disappears or worst, tends to get choosy on the route they want to take. ...I swear, the moment it starts raining and you try hailing a taxi, all the empty taxi's that passes you would already have a hand signal, as to which direction they want..If you're not going that way, they won't let you ride. And if you're lucky enough and some taxi would stop in front of you, if you see that their windows are down, be ready for a lot of negotiation and this conversation...

Taxi Driver: San kayo? [Where are you headed?]
Passenger: San Juan
Taxi Driver: Magkano binabayad nyo haggang doon? [How much do you pay for a trip going there] or Ay, baha ho kasi doon [The area is flooded], or worst you get to see the driver shaking his head.

Now, under the norms, this should not be the scenario because taxi's are supposed to accept passengers and bring them to their destination, safe...And aren't these the same drivers who keep complaining that they are no longer earning enough for their families? The same driver's who when the sun is up and nobody cares to take a taxi, would stop right in front of you even if you never called for them. Now I am confused and more furious....because with this kind of attitude, I do not see why these drivers and their operators still ask for increase on their flag down rates, when the reason why they consume a lot of gasoline, is due to the never ending rounds they do choosing for the passenger who just want to be brought to an area that is close enough that you can even walk going there....I'm thinking, if it's through their passengers where they get their income, and they have the nerve to shoo away passengers, then maybe these drivers do not need money anymore....So, what's the point in requesting for flag down rate increase? And still they ask their passengers for additional money other than what has been reflected on their taxi meters......that's CORRUPTION....only in the philippines...haaay!
