In India I once hailed an auto rickshaw and had him take me about half a kilometer in the rain. I asked him in American-accented English what the fare was, and he said 200 rupees. I started yelling at him in perfect Bengali that I wasn't born yesterday even though I am a foreigner, and that I spend a lot of time in India. He countered with an offer of 10 rupees, and I gave him 20 because I was laughing so hard. The sad thing is I know that the 200 rupees must work on some people.
