I suspect most of the current parlours are very reliant on the local footfall, and that setting up a new parlour in an out of the way location like a farm without locals would be very expensive for the parlour for at minimum the first six months while they built up their client base.
I don't think £80 per half hour would work as a few of the current parlours almost already offer that to WGs now with the right extras. Unless there was an expectation of OWO and Kissing bringing that amount up to £100 per half hour. It probably makes more sense to charge £100 per half hour and say OWO and Kissing are built in as the standard of the parlour is GFE, but are at the WGs discretion. You actually want to be unpopular with the unhygienic punters who would be worried about losing out on this.
But if there was a customer base willing to pay £100 per half hour for top quality WGs at an upscale parlour I think that we would have already seen it happen via an agency with an incall flat.
If we look at Divas in Stoke, Brooklyns in Crewe and Cheshire Elite in Crewe, they all charge £50 per half hour but then also charge £20 for OWO, £10 for Kissing and then have a laundry list of other extras.If you read reviews it is not uncommon to see £80 to £100 being charged per half hour for standard GFE bookings at these locations. Despite charging these rates none of these locations has a rota of top quality WGs such that they feel like an upscale parlour. In fact they have arguably worse rotas than most of the Manchester parlours.
Similarly, out of the various Manchester agencies, none of them seem to be successfully offering a premium experience at their premium prices, otherwise we would see better reviews.
There are a small number of WGs currently in the Manchester/Crewe/Stoke parlours that have the looks/age to justify a £100 per half hour price tag, but do any of them actually deliver a service to match? There are plenty of high service WGs around based on our collective reviews, but based on those same reviews, I think they lack the looks to justify a £100 per half hour price tag, either being too old or having other physical flaws.
I think a big issue for us punters with any new upscale parlour is how many existing parlour WGs in the area would incorrectly think they were worth the higher fee and try to work there.
