One I have recently found is Arlington Red Top Cab in Virginia. First of all, a living human being answers the phone when you call. If you want to be picked up they key in your phone number and ask if you want to be picked up at your home address. Not a problem if you don't, but a nice bonus not needing to repeat your address every time you call. Then, they send you a text when a cab has been assigned, is a mile away, and is at your location. Each text has the number of the cab so if more than one person is waiting you know easily which one is yours.
This may sound like a relatively simple process, but the fact of the matter is that it is often the simplest things that get overlooked. What makes them great, is they are there when you call, they know their customers, they keep you updated through the process, and they don't make you guess whether they are responding to your call or just driving by. I wish I could say that about myself 24x7!
