Cab drivers have long been kicked around in DC. For years there was a zone system that favored anyone traveling from a Congressional office to a Federal building. As in, it only cost three dollars. Talking to those cab drivers was great. The powerful riders spoke as if the cab drivers weren't there at all, much less that they could understand what was being said. Think: what elitism! What information! What fun!
So no surprise that Congressional pressure resulted in DC cab drivers getting stiffed on fair rates for years. After all, they were the help.
So now cabdrivers have found their teeth. Good for them. And let future candidates take heed.
