Why tell them directly?

So they know because you told them. I doubt they care to read the boards if they’re super busy entertaining with, so much traffic they can’t clean up. When I had three private incalls they were clean AF. Cleanliness is a must.

a trash can full of used condoms.

...you were carrying your own towels.. How do you know the one you used to wipe your ass were freshly laundered ? lol

 
Maybe don't book a girl that runs her shop like a meat factory or do an outcall.  

 
You should drop her a review and slam her lack of cleanliness.
