As far as possible, I avoid taxis unless really necessary. I'd rather walk or take the bus/mrt. I know cab drivers are people just trying to make a living too but really, they can be such a put off with these tactics of theirs. Sometimes I feel sorry for them. They must be so lonely that some are willing to blab to anybody in their cab regardless of whether the passenger is actually listening or not! I've had drivers go on a religious tirade to lamenting about the injustices done to them (poor things) and I'm too nice of a guy to tell them to shut up.
Another reason I avoid taking taxis is that nothing triggers the rage virus (ala 28 days/weeks..) in me more than waiting for a cab long time and seeing someone else blatantly plant him/herself a few metres up the road from me and stop that cab I'd been waiting to come along for! (GGgrrrRRoar!) Of course I understand that the driver has no way of knowing that I was there first. Therefore to save myself from all this grief, I avoid taxis.
