Similar experience here a couple weeks ago.
Thought I had made an appointment and said I was about 20 minutes away or so, I actually got there in about 30 minutes so I don't know if that pissed her off or not but I never got a response to my calls after I arrived...
I typically don't like to book with the 20 somethings so I was not overly disappointed when communications broke down, it just kinda reinforced my reasonings for avoiding these younger girls. I'm not saying I was in the right here, there was no firm commitment on either end, just a request to call when I arrived, she may have been busy, who knows, it's just I never got through and my window of playtime is often not extendable.
Cool
