GFE and Phone Conversations
I usually just use the phone call to schedule and I kind of let the girl set the tone. Usually I can tell if they are a pro or not with the conversation and where it goes.
If I am scheduling an incall I ask a few leading questions about the location and usually by the responses I can tell what type of provider I am dealing with. I have found if you attempt to turn the call into a deposition most of the providers have a short attention span and will just start telling you anything to get you to show up and get the fee.
And then there is the factor that some providers have one set of rules for certain people and one for others. I know one of my regulars and her boundaries vary greatly by client. I have called a few and ended up changing plans based upon attitude of a phone conversation.
