I’ve never been to a shop and only done Private.
Agreed your going to get a real mixed bag out there on quality and time and yeah, you end up with those chewing up time or ending your time short.
However I also found those who will give well more then an hour that I paid for and the experience that keeps me coming back for more.
My game is, on those who cut you short on your experience then you just don’t come back.
Can’t see how it’s a good business model for them.
Out of that though, ive found those who give you all you wanted and more.
I think you just have accept your going to get below average Privates a bit, but your also going to get some real finds too.
