Each to their own - some members here seem quite easy going, whilst others seem a bit draconian in what they will and won't accept.
Personally, if I get a neutral or negative service, that particular girl's history so far as I'm concerned. I've been lucky in the last 6 months or so, and the worst I've had was a neutral, but that could change at any time, of course. It's called punting for a reason, although careful research helps of course.
What I personally won't tolerate under any circumstances is when a confirmed booking is bumped because the girl has obviously had a better offer. Blacklisted and I will name and shame on here. Again, luckily this has only happened once in the last 6 months or so. Stacey Nice Summer - blatant.
