Exactly my point. A car salesman "orginal course of action" is to negotiate. Commanding voice is used to shade his throught process is headed. Its definitely open to GM interpretation, since the rules in the book are clearly for hostile situations. Again, clarify with your GM how they prefer to handle the power. As a GM, I'd let you use it as I mentioned above. Critias, seems to be an RAW guy, he probably wouldn't let you. Just boils down to how the GM feels it should be used in play.
The rules in the book are clearly for hostile situations because, in my opinion, there are other Adept powers to handle the not-hostile situations. Barking an order at someone is confrontational and obvious. Confrontational and obvious are short term, not long term, plans. You use Commanding Voice much like you use Intimidate -- it's an immediate problem solver, not a slick, multi-step, problem solver.
Social Adepts already have a bunch of good ways to get a great deal in a negotiation. Heck, between Improved Ability: Negotiations and Kinesics they can
already double dip, in fact, to totally blow someone else's die pool out of the water. Letting them
triple dip, by slinging a ton of Leadership dice around in order to compound their die pool is just asking for trouble, in my book.
When the power specifically states that the target will "quickly reassert their wits," it seems to me like there's plenty of time for a used car salesman to get his crap together and realize he's being ordered around and throwing money away. Buying a car is a multi-step process with plenty of paperwork, bookkeeping, and back-and-forth to it, and often more than one salesman/financier involved. Ordering someone to "give you a deal" is like ordering someone to "bake you a cake." Sure, you might roll well and browbeat them into doing what you want for
a single action, but after that they've got no magically compelled reason to
keep on being stupid for you.
If I were to jump into a car right now and use Commanding Voice to tell someone to "Drive me to New York," they should either sit in their car being confused, or put the car in gear for a few feet (their next action) before they hit the brakes and look at me like I'm a moron. If I
con them into giving me a ride to New York with some good role playing and a whole series of Etiquette and Negotiation rolls to approach them at a gas station, ask where they're going, influence them with Kinesics to adjust my body language and tailor my request to their ability to actually give me a ride, over time, I might be able to get them to toss in a round trip.
To me it's an issue of the immediacy of the command, and how quickly -- right there in the rules -- targets are stated to snap out of it. It's a matter of using the right tool for the job.
