I used to treat my punts almost like sex with a civvy, as though it were a mutually desired act.
I gradually gave up on the thought of getting the girl to orgasm, RO etc. I now focus more on non genital erogenous touching and kissing. If a girl really gets in to it, and she smells fresh, I may consider RO, but that's an exception.
If a girl doesn't orgasm it doesn't bother me, nor reduce my enjoyment. I take the view that she's probably had several dicks already that day and spent herself.
I have have been surprised recently, by two SP's who said they had an orgasm when they weren't expecting to. Before one of them got on top she complained that I hadn't given her RO, which she said she needed to get going.
As for being clean, having the right money (no haggling) being on time, I expect that and do that myself as a given.
Sadly, some SP's decide to advise you of eggstras only when you get in the room, often contradicting what has already been confirmed on text.
Some SP's haven't washed after the previous punter, I remember getting the minty aftertaste of what was leftover of another punter (chewing gum no doubt) when licking a girls nipples.
Too many girls fail to be ready at the agreed time, "I'll be five minutes baby", that turns in to 30.
