£70 for a 60 YO is a bit much.
I think 60 YO for some is being kind.
There's been a group of Hungarians in that area for a while, charging £50 for 15 minutes and £70 for 30 minutes.
A ridiculous amount for what is, let's face it, a very old woman for a sex worker. Especially for an old EE, but surely reflective of that fact that it isn't London and punters will pay it. Market forces I guess. Otherwise they couldn't charge that. Some of these women come and go. Others have been around for quite some time, in different iterations like the one above. Sergei obviously knows his market very well in that area.
For me, no more than a £30 - £40 15 minute quickie or perhaps £50 for a full 30 minutes, so would never interest me. I'll stick to London!
You'd be better hopping on a cheap Wizz Air flight and pumping a few, for a long weekend at £20 - £30 a pop, which is what they charge in Budapest!
Plenty more competition in London and at more 'realistic' prices.
