I've seen a few C-N providers and have found them to be more attractive on average.  However, I'm starting to see some low performance scores.  Do you think they're being over-booked?

I always book early in the morning.  By the time evening comes around, any gal that has serviced a half dozen guys or more isn't going to have much more to give.

The real problem is you no direct contact with the girls so if and when things change there is usually no way to contact you, the customer.

And in my experience the contact people will just cancel on you rather than explain.

Yea, I had that happen when I drove all the way up to the SFO area.  Got to the hotel, knocked on the door and didn't get an answer.  I left and saw an email from C-N that came 30 minutes before the scheduled appnt saying that the provider had fallen ill and would have to cancel.  Do these folks think we have our laptops on 24/7?  I haven't used them since.
BTW, enjoyed reading some of your reviews.  Seems we hobby in the same areas (SJ, Gil, SCrz)

Yes we are in the same area, if you of any hotties down here let me know and I'll do the same.

As for the CN, there communication efforts are horrible!!  I drove to S.J. one time and told them to call (from my number on the app. form) and the idiot dude who was in charge of the S.J. girls e-mailed me.  It's hard to check e-mail from there when I live an hour south!!!!

So they said they would give me $50.00 off-I called them regarding a special rate of $250 which they had posted, which would have been then $200.00 with my discount-they said not on special rates!  SO I TOLD THEM TO GO FORNICATE WITH THEMSELVES & NOT E-MAIL AGAIN.

From talking to the girls, a lot of guys are actually flaking. I've been fortunate enough not to have been flaked on, and extremely fortunate to get great service. Has always been worth the drive (Oakland to SFO or BART to Union Square) and the $$$.
