When they ask you what services you do, so you list the ones you don't do and they say " ooh that's a lot of donts". Like wtf how is no fingering or no anal and (owo/cim at discretion) a lot of don'ts?? Frigging greedy cheap twats! If you read my profile you'd bloody know.
I've noticed it's always the large, horrible looking guys that think they are sexy af that say this

When they cant find my clit, and it's right in front of them.
When they say "go slower" "slow down" and you're barely riding them at 3 mph! They do this to take the piss and try drag out the time.
Or when they say they want to go toilet after a booking. You don't hear the toilet flush. So when they leave you go check and there's fucking chewing gum at the bottom of the loo!
