I'm training newbies again, too. LOL No offense fellas - quite the contrary! There's just been an influx of newbies on both the hobbyist & provider sides, and there have been some lost opportunities thanks to ignorance. I think it's important for newbies to see a seasoned provider who is willing to "show you the ropes". Things like "no discussion of activities or pricing", protocol such as how/where to leave a donation, and the acknowledgement that there will be differences from provider to provider so there's a need to be adaptable are all important in making a newbies hobby experience less frightening. Nobody likes to feel ignorant. I sure don't!
Besides the P411, Date-Check, Room Service 2K, and similar verify service options, there are methods that are not invasive that will put a provider more at ease when screening. Just realize that if you're approaching a well-reviewed (20+ or more positive reviews) you should be willing to share a little info. Those reviews are vouches essentially, and all we're wanting is some reassurance that you're not LE or a serial killer. :P
Play it safe everyone!
