Just wondering....

that lady gives you a location & time to call her.  It might be a hotel parking lot or an intersection.  You call & she gives you directions from there.  If you don't show, she hasn't given her exact location away.  
I've been delayed in traffic so as a preventitive, I like to plan to arrive early.  But sitting in a hotel parking lot, reading the newspaper draws attention from Hotel Security & Patroling LE.  So I withdraw to the coffee shop, timing my return.  With my Favs, I often call from the coffee parking so I don't have to call from the Hotel lot.  Once it almost backfired as the lady looked out her window & said "I can't see you!"  I was at the other end of the lot & quickly parked...

give you a location near her incall, and when you call she will give you the address.  If she is in a hotel, she will tell you what hotel, and when you call again, she will give you the room number.  

It's all part of her keeping herself safe.

If you have my exact address and get delayed or decide to go to dinner or whatever first and I figure you are not coming,  I might accept a date with someone else and I dont need you knocking on the door and killing the mood.
