I honestly do not like this... I try to avoid this as much as possible.
I ONLY give my number to client AFTER confirmed appointment and/or screening. I feel like client and provider should ONLY have and use phone number for SESSION, unless you and that client have that connection... Well I had this guy ask for my number and me being foolish I gave it to him... He did not ever make appointment. He just kept calling my phone at the oddest times of the day 5 or 6 am and would just want to talk and then would get mad that I wouldn't talk to him.
Really dude you mad?!?! You didn't want to set up a session you just wanted to talk not even meet for a cup of coffee... I call that a CREEPER
