Discussed this with a regular in C.C. recently. She did make a couple of valid points a) What's the difference to visiting a house or flat with nosey neighbours?, and b) She's paid to fuck and they're paid to clean (that's prossie logic for you).
And yes, there was a couple of cleaners, but they don't know me and I don't know them as I always punt miles from home, so no problem as far as I'm concerned.
