Thanks OP for the update warning.

If it's the same 5'7", mid-30s, sz 10-12 Sarah from the last 5 years with fake tits, botoxed face and chiseled features she has always demanded more for her limited manual services because she was the looker of the lot.
All the girls there want too much money since way before the pandemic. A few years back they were the same prices as the Chinese parlours in the area, reliable, friendly girls working on rota, then some of the girls left and new blood with bad attitudes to extras came wandering thru and those that remained became infected with the same malaise. Best left as a legit salon and take your randiness elsewhere (regulars who got in with any of the old hands remaining may still get yesteryear prices).
Sadly most parlour options in Clapham, Tulse Hill, Camberwell, Crystal Palace, Brixton, Tooting, Streatham, Colliers Wood, Wimbledon, Morden aren't much to shout about anymore.
Best to find a 30 min WG for 60-100 and have a guaranteed suck and fuck with extras, the most you're missing out on is a mediocre massage.
