I've been once and had a young pretty Indian therapist. She says she doesn't mind looking at men's bollocks because her other job was working at an old people's home, however she won't "touch it".
With plenty of time left after a very average massage, she asked where I'd like her to massage and knowing that she wouldn't touch mini me, I said feet. And she said that the therapists weren't allowed to do feet here

I was like wtf?? So she volunteered to go and double check with the male receptionist, left the room for a few minutes and came back saying he's said its okay this time.
Needless to say I never bothered returning.
