OK, I'll address this too:
"What if I'm never let to speak the tech that works on my car?"

Being that techs are paid "flat rate" (only while working on cars, not talking, not test driving, etc) it's to the dealers best interest to keep the techs physically working on cars at all times. It's the service writers job to talk to and perhaps sometimes drive with a customer when need be and/or if asked to verify a complaint (like a noise maybe). There ARE times when it's better to have a tech meet with the customer and drive with a customer if the odds are better that that way, he'll hear the exact noise and hopefully know the cure rather than possibly not knowing exactly what the real complamnt is. This might sound like I'm contradicting earlier statements as I know that you can't always talk to the techs everytime about anything BUT if you need to or want to, I can't imagine why a service writer would object unless he/she feels that you'ld be wasting the techs time or the tech is currently too busy to talk to anyone. That also happens, there are times when the techs are working on several waiters at once and they all are in a hurry. At those times, the techs can't really talk to anyone as the pressure is on.
