Two new Chinese massage places in my SE town over the last year. I've not been so no idea if they offer 'extras'.
What you have to remember is that there has been a semi-organised push by chinese criminal gangs into more and more of the UK sex trade.It's an easy route for them to launder money - a massage shop can be a front to disguise takings from drugs, people smuggling and other criminality, just needs the accounts to overdeclare the takings and the real source of the money is hidden.
Spot on SB. Any cash business is an ideal front for money laundering. Other examples include Nail Bars and Car Washes (the type where a team of workers turn your car around in a few minutes)
And Turkish Barbers (although not many Turks running them) considering the number that seem to be popping up in every town I visit!
From just £36 per year
