Could you tape your appointment so that when he tries to charge you hundreds you could prove to him how much he rambled? Say you rambled here where a simple yes or no would have sufficed. I will not pay for that time.

He could be aware that he rambles BUT if he's the only option what are people going to do? That's the problem with someone that has a monopoly they can pretty much do whatever they want and charge what they want and you have no choice if you need that service. Good luck to you.
