The 1st mtg I had with my prov. was cut short due to technical snafus and prior obligations.

But the 2nd mtg?  Ended soon after I came....at least 15 if not 20 minutes before it was supposed to end.  Not because of emergencies or pressing prior obligations....this time, it was just because I came.  Her attitude (at least towards me) is that once I come, "what's the point?".  

So does "not being a clockwatcher" mean shorter-than-planned sessions as well as longer-than-planned?

If your clock has water its likely not working.

No, it means she is a "one and done" type of provider.  If that works for you then continue seeing her. If, OTOH, you are paying for an hour and not getting it you may want to look elsewhere for companionship.  Talking to her about it would be, IMHO, a waste of time.  The last thing you want to have to do is twist a provider's arm to give you what you paid for...

My advice, move on, do not see this provider again. And try using spell check.

Yep, there's sort of a different golden rule in hobbying than in the everyday world.  It's "if you don't like what somebody wants to do for you, go find somebody else."  And there's always somebody else, if you have the $$$$ and the time.  But it shouldn't be hard to find someone who'll do more than one pop or who'll hang out after one pop for $300 an hour or so.  Look for a well-reviewed GFE.

That's the thing...she WAS well reviewed.

Well, I just got a call from her and she's pretty pissed.....it's become one of those he said/she said nightmares. "You're badmouthing ME?  I'll bad mouth YOU!".  I haven't named her and only PMed others who've reviewed her (on another site) asking how their experiences with her compared with mine.

Should bring an alarm clock to these meetings....

Clock watcher is an over used term.  She's one and done - not MSOG.  If you want MSOG, make sure it's available.  If it's on her reviews that she does MSOG and she's not doing that for you, mention that in the session and if she doesn't come up with something reasonable, say it in the review - "I only got one when other reviews claim she's MSOG.  Must be YMMV."  or, "she has changed her policy/menu and is now one and done, no more MSOG as in previous reviews."

BTW - if you catch a provider peeking at a clock, that's not a clock watcher either. We have schedules to keep and are often having such a great time we do have to peek every now and then to keep ourselves in check and our schedules in check.

Actually a good provider is an excellant time manager.  Some use clocks, one Fav has a small clock that I did not see for the first year!  LOL.  
Others use times music tracks or other cues to keep the activities on schedule.  Not a clock watcher, should mean +/- 5 minutes is not a big deal to them...  
My Favs will lay with me on the bed & cuddle until it's time to dress.  To me this is GFE.  

Chemistry is not guarenteed.  If you are not getting what you need, then you should move on.

I use "not a clock watcher" in my ads.

To me it always meant - I'm not going to kick ya out five minutes after you pop, I'm going to let you stay for the entire session time wether you want or can pop again or not.
