Thanks for the kind words Ahlungor, I've been following your exploits for a long while now. Yes, I do remember you writing an AR about Chequers some time ago too. My lasting image is of you wiping your hands on your hair so you could try and get some grip! Very funny!
I have a friend who tried the King massage before I did and BBBJ was on offer although she did ask for extra payment which he declined. She went ahead and did it anyway. I'd wonder about how paying extra would work there considering that your wallet etc is locked in the lockers back out in the change room. Chequers is still the more expensive option than other massage places, but the facilities are certainly top class and I've found it a good place for something special every now and again.
