I find the ones who ask to check that you will do owo are the smelly cheesy ones! The 'unassuming' types just call, book, turn up and are grateful/appreciative. Same with French kissing, I find if they rattle on about it before the booking chances are they will turn up with shit for breath 

I would agree with this to some extent,these are the guys who make comments about other service providers not kissing and then you realise why they have probably been refused before.Bad breath or something similar.

That was always one of my tricks!Plus using a load of strawberry lube/baby oil to wank them and then insisting I wipe it all off before putting it my mouth.

I carry strawberry lube for this precise purpose and always give them an erotic hand job, using lots of it, before my mouth goes anywhere near..and this is for the 'apparantly' fresh and clean ones ( because they very often touch their todge after a cheeky cigarette too - vile!  )

The Great Unwashed are asked if they are looking for OWO? "Oh fab!  Just nip and give it a quick wash in that case! " 
The tone indicating the order, not request 

How do you cope with punters that are stinky?
Had some old guy other week said he was clean what a joke , started giving him oral and do not know how I stopped myself puking up on his dick , his balls stunk like sour milk gone off , tried hiding breath as long as , all eye make up running was so glad when it was over , can’t stand when they like that and I wash myself several times for them , but a bit of whiff must be the norm for some of them .

When I'm gonna give them blowjob and they stink down there or I see dick cheese I always put condom on. Then there are 2 possible reactions :
A. They don't care and enjoy themselves
B. They ask me to take it off as my profile says I do owo. The m I always say: I do owo only on freshly washed guys. And they run to the bathroom.

A few times I had a situation where clients went to the bathroom just turned on the water and went back as stinky as they were before. In that case I refuse owo.
No way I'll put that in my mouth!

I had a client yesterday. Cute guy, young. Asked for towels to shower as he had just come straight from work.  Thought to myself, "Impressive - asking for a shower without being prompted."

He comes out after a short while and he smells good and clean. Then he whips off the towel and ask for oral.  OH MY GOD!  The stench made me want to retch my food back up.

I looked at his cock in detail and there was no cheese, only a little bit of pre-cum.   

So I jumped up and got a wet towel and some body wash and a packet of wet wipes and cleaned him up; guess what? The stench was still there.....  I concluded he must have a condition and refused oral.

A clean and freshly washed cock but yet still smelly
