I tend to let them know what theyre doing is making me uncomfortable and if they continue i terminate the booking
I cant stand someone gazing into my eyes, or saying creepy things or consistently creepily telling me how hot i am! It gets a bit much! Once, twice, fuck off!
If you just take it, they expect you to do that everytime.
I normally let them know at the end of the booking, that i wouldnt be comfortable in seeing them again.
