Been using Discount Cab for over a year now. Never had an issue drivers always know where they are going, and they don't snap at me when I want to pay using my card like over cab services.
Never had to wait longer than 20 mins (avg wait 8-15 mins) on a cab even when I call them last minute when I need to be at the airport even when calling at 4:30 am when my flight left at 6am.
Well I take that back I had to wait almost an hour one time but I wasn't in a rush to be anywhere. But other than that the wait isn't very long at all.
They are my usual go to when I head down to Mill or Old Town to drink. Because we all know DUI's are NO joke in Phoenix.
