YMMV -- your mileage may vary.  But what, pray tell this newbie, causes the variance?

For instance -- I saw a lovely provider who should have been a perfect GFE.  This was before I had TER access, so I will admit to not having read reviews (I've since learned that).  But when I did read her reviews, several described services provided (DFK, BBBJTC, CG -- damn I hate these abbreviations, but what the hell ... when in Rome) that I did not have offered.  In fact, I was told specifically by the provider that she had 'rules' on these things and didn't do them.  And that I had my choice of two positions and that was it.

So mostly to providers out there -- but also to any who can answer:  What causes mileage to vary?

I can understand if I show up unshowered, having just had scampi and spinach (still in my teeth) and a cigar, that I'm not going to get a kiss or a french lesson.  But is there anything else going on here, other than perhaps, simply, that she felt no chemistry??

Many thanks!!!
