Attempted to order a cab for my gf at 1 am from Drinko to a few blocks down Hal Greer. Was told she'd have to be the one to call. Didn't seem to matter to the dispatcher that my gf had no phone to use. Why they would have a rule like this, I have no idea. Can't be a theft sort of thing, given a person could just call and have them drive to an area. So unless you have a way to contact for your own ride, you're out of luck.
