Ethics aside, I'd expect the tactic to backfire in most cases, and especially if you want a natural GFE type experience. Few perform better when they're expecting to be judged, especially young people. I guess only about 1 in 10 come across better at an interview compared with how they are in regular interactions.
At least for GFE punters, if you're looking to get the best out of the lass, starting by giving her a 10 min massage consistently works great in my experience - if you don't have massage skills, you'd need to read up / watch a few videos first. And then be domineering, but in a benevolent, low key & non rough way. It took me a few years to perfect & doesnt work every time, but recently I've been having the best sex of my life - in some cases WGs getting more physically turned on & putting much more effort into pleasing me than the few civvies I pulled back in my 20s & 30s, when I was in much better shape than now.
As for lasses asking for a review, about 1 in 4 do that with me. Mostly Diva lasses who I think always meant a Diva review, but also 1x brothel (HoD) lass & 1x AW girl. Always at the end of the punt though.
