Yes we do. Like doctors we have so many that are specialised in different anatomies - ENT, spinal, kidney, heart, neurology etc. Having many shops and breaking them down into MLs that offer different specialities help - NHJ only parlour, CBJ + FS parlour, special needs FS parlour and special kinks/request parlour.
And maybe one day there'll be a shop that services Indian only - the Indian folks will be happy and not complain about shops or girls being racist.
Funny enough we never see anyone complain that most Swedish massage are not performed by Swedes lol
