I'm obviously pretty new to all this but recently I had a experience with a Asian TS at a LAX hotel who said she doesn't get topped after we had started.  Pissed me off but I still got off.  I'm leaving that to just a bad experience with a TS who obviously didn't feel like me and was screwing me over cuz I wasn't a big burly guy.  I'll leave it to karma to catch up with her.  However I'm wondering what are some basics to cover beforehand to better ensure getting what I paid for.  
What do you guys do?  Specific questions?  requests?  any help would be greatly appreciated.  Thanks in advance.

I found that once its established that you are not LE and legitimate session is about to occur, its best to be clear about what you want BEFORE you hand over the dollars. If you get I don't do that and its not to your liking that's your only opportunity to move on. Also, if you get there and the person who answers the door does not like the person in the ad, that your only opportunity to decline. If she looks better you're in luck, 9 times out 10, that will not be the case. That has been my experience. I'm sure others will chime in.  Oh, and be sure to write a review and let others know!!!

if we know who the girl was maybe someone can share their experience too. if your new maybe you missed something in her ad

you are supposed to do?????  Go to TER and check her reviews---you going to do it more than once a year?  become VIP   READ   READ   READ

or get some really good track shoes so you can RUN    RUN   RUN   but it's too late once she has your money.

yep, check all the reviews you can.  the best escorts are pretty straight forward as to what they will or won't do.  this is also where i have found it best to visit early.  even the best intentioned gals will tire out, who can blame them.  it also helps, in my opinion, to make sure you are clean and well groomed, you would be amazed what a little clean breath and soapy fresh skin will get you.  i like to come a little shy an inexperienced, comes in handy since i like a versatile gal.  seems they like to have their way with my cute butt and i get theirs too!!

Thanks for all the responses.  I'll definitely be better prepared for the future.  
Yea I take total responsibility for what happened but it's not a big deal.  Like I said I'm new, still learning and I just recently discovered TER.  
I'll write a review soon.
