I am close to stopping to be newb friendly as well, but don't want to alienate good clients.
I have met many awesome newbs, and have had great sessions. However, as of late, I am finding many of them are annoying time wasters.
Guys, it is not ok to make an appt with someone, then "change your mind" 30 minutes later, or give them all your screening info, they screen you, come back, and you suddenly decide sorry, never mind.
The more we put the word out about them, hopefully, they will start to understand that this kind of behavior is unacceptable and will not get them very far in this hobby.
Also, running into many newbs who don't have references and refuse to offer any other info whatsoever to screen. I am unsure what must be running through these men's heads, that they think they can secure a session with literally no screening whatsoever. You wanna go swimming, you gotta get wet.
