The before and after contrast was so great with one man I stopped seeing him. He did it on every visit (dozens) and I just thought I don't need this level of rudeness.

I don't think I have met once since who was so awful so now I just let them go silent then leave but I am still polite and take them to my door with a smile.

I'm generally quite chatty so this has rarely been an issue for me. I also see a lot of younger clients in their 20s (as am I). The young ones I find easiest to talk to as we have more common interests.

My go-to line after sex is: "so do you have anything planned for the rest of the day/weekend?" It's an open question which I find gets more response. And if they say "not much" then I just tell them about what I've got planned or what I'd like to do. Sometimes if there are events in the area then I mention them too (Eg local football team playing).

Depending on the vibe I make jokes. It's in my personality to banter with people. It is often about the vibe.

Rarely does a guy leave without a chat afterwards although I have had this guy who booked an hour, ended up being really late so he said he will refund me the difference. He gave me £200 and left after 15 mins after he came. He ran for the door before I even got the chance to get him on some small talk Suddenly wished all of my bookings went like that one 

Some time ago I realised that a lot of clients are just waiting for the "so what are you doing the rest of the day" so I stopped saying that kind of thing.

Hair stylists do it and it is so predicatable.

I once mentioned the drastic change in the weather as one man was dressing and he gave me such a look of sarcasm but he did his best to not roll his eyes at me. 

I've only had the huge personality change a handful of times, but it is disconcerting when it happens.

I am generally very business like and if they get up off the bed and put their pants on straight away then I follow suit and don't talk unless they are talking.

I have a ready bank of sarcasm so if they start dropping what they think are condescension bombs they will get their arse handed to them.

Funnily enough none of the tossers I'm thinking of came back...

I had one of these last week and it was HORRIBLE - I was really uncomfortable so started awkwardly chattering away, in the way that I do when I am nervous. He must've thought I was a right dick. In the end I just stopped talking and let him get up and leave; probably more comfortable for both of us. I am so used to clients having a blether with me that when they don't, I find it very odd. Disrespectful, almost.
