If it's a regular, they understand, but usually it's the ones who are new to a room or to cam sites in general that will leave. And agreed on the 30 second thing, that it should be billed. There are a ton on there who will peep in and out constantly, although it is funny when they accidentally stay longer than the 30 seconds and get billed for it haha.It does suck. But, at the same time, it's all part of the business. So, I get it. Of the models I discuss privates with, most occur when we discuss them. Or, if I don't have time, I will let them know I am short on time and planning for future but will do next time. These are all models I've had some interaction for a while with, and most times at least a couple of privates with previously. So, I'm not a new person to them by any means.
I'm sorry to hear it's a shitty situation on the 30 second part for SM models. Seems like it's a waste of time, and should be billed accordingly. MFC, and I think CB, will charge for every minute. What makes it worse is that typically those who legitimately want an exclusing with you will leave. Though, I would think they'd want to stick around if they really wanted it?
Sadly, just a negative side of the business we have to contend with.
That said, if it makes a difference, most of us models do care about our regulars and it's a huge peeve when something happens that results in them having to wait, whether it's a short or lengthier amount of time.
