A gentleman may be too polite to say anything, same too with a nervous punter or a newbie. BangersandGash struggled to get a word in edgewise if you believed his review and he is an experienced punter. Having to tell an escort to put a sock in it can ruin the mood and not everyone has the skills to do it tactfully. A good escort will make moves to bring the action onward if a punter seems unsure of themselves, not just sit there talking about themselves or expecting the punter to make all the running. The escort is supposed to be the professional here.
I wonder how much the early post of James has influenced following posters like yourself. His comments are valid in part, still unusual to see him taking a position akin to what has previously been termed white knighting. It does make you question where the little coward label belongs here and how you would have posted had you gone first with your own reply before seeing how the thread was panning out and agreeing.
If she used time wasting tactics on him, and it compared poorly to his other bookings then it is a negative. Punters prerogative to rate as they experienced something, that is why multiple reviews are beneficial.
I agree. I'm surprised she's had so much defence especially from unusual sources.
If he felt rushed or the talking ate into his time then his review is extremely justified. If it didn't then it's less so but even then not everyone has loads of spare time and many may well want a half hour punt to be just a half an hour (on many occasions that's true for myself). Also, as you say, the escort should be the professional and has to accept at least some responsibility especially given her experience, even though of course, she can't be expected to be mind reader however I'd be surprised if she couldn't read faces, tone of voice and body language at least fairly well. And of course, it's his prerogative to rate it how he sees fit, he clearly felt that the talking was actively annoying or at least made her seem less sexy, this is a totally legitimate viewpoint (even though, yes, he should have said something but as you say, not all guys have the confidence or tact to do that).
Just to be clear though, this review wouldn't personally affect my decision whether to book her or not although some other reviews don't either (for many WGs) but I still welcome the additional information and perspective (even though in this case it's not particularly news to me - it still doesn't hurt to be reminded especially for punters who haven't read many of her reviews or seen many of her comments).
