I have never intentionally overcharge my passengers in my 16 years of cab driving adventure. If I am going to charge you more I will tell you that up front on how much the fare will cost if the ride is out of the ordinary, like if you wanna bang your woman in my back seat, or if have to drive you all over the place looking for hookers, you know, shit like that and in that case the zone system is not going to fly so I will tell what my time is worth in advance. Squeezing a buck or two of you is not going to change my life and it is the WRONG thing to do, most DC cab drivers are honest guys, but like any business there are few bad apples and that makes people suspicious of cab drivers, especially here in Washington DC because we don't use meters and use confusing zone systems.
So today I will throw a bone at you on how to be an intelligent cab rider if you live near Connecticut and Florida near north Dupont or Kalaroma heights. Make sure to walk a few blocks and flag your cab at the corner of Connecticut and Florida because it could be three different zones 1, 2A, and 2B from that spot. For $6.50 you can get a ride all way to Union Station, Capitol Hill the House and the Senate, all over down town, South west north of E street, Washington Hospital center, Columbia heights, National Zoo, Vice president's mansion, Georgetown main strip and Georgetown University, Kennedy Center and the Watergate, George Washington University, all over Shaw and on all way up to Georgia and Randolph. That's why I call it the "Golden Spot" for you passengers not for us hackers, its more like a "Give a passenger a free ride Spot" for cab drivers so don't be surprised if some cab drivers simply ignore you and blow you off if you're standing at that spot especially this Diamond Cab driver I know with a fucked up hair and picking his nose.
Don't forget the homeless.
