So, 5 days ago I had one of my wisdom teeth removed. The pain was doable but yesterday it was getting worse and I ignored my body telling me it wasn't feeling ok anymore. I thought I'd do my two bookings today and would go to the hospital on Wednesday but this morning my saliva was green, I had a foul taste and my first thought was it might be infected.
Called with reception of the surgeon and they told me I should come immediately. So I mailed my two clients on 8.30 AM this morning (one appointment was on 11 AM, the other at 1 pm, telling them my situation and that I'm sorry but I couldn't do the session because of the above. While one was a bit understanding, the other got totally passive aggressive (like mailing with fuck and angry because he took a day off for our one hour session). I cancelled on him once before 6 months ago because of a migraine, and 3 months ago he cancelled on me. He is saying I'm not reliable, and blabla. He suggested I could do the appointment after the hospital but my incall place is a 2,5 hour trip by public transport and I already cancelled the location and have to pay for it as well. Besides, I'm not sure if I can do a session at the quality I normally give so for me it's a no go.

My stomach turned because I greatly dislike this mess with clients and particularly conflicts. Besides, I offer kinky sessions with kissing and I pointed out to him that this wasn't possible now.
Now I feel like I have to make it up to him, he is also insisting on a solution in an unpleasant way. He and I played only once (besides the two cancellations) so he isn't a regular who I would like to keep. But I kind of feel obliged to make it up..

What would you do?

You come first. Always. Let yourself get completely better.

Does he know you've had your wisdom teeth removed?!
That's like an operation, and I know quite a few people who have been in lots of pain and really unwell with it!
The last thing you'd want to do is work!
What would I do? Tell him to eff-off, he's got no sympathy for you, he sounds like a prick and not worth keeping as a client! 
Take a few days off and let it heal properly, and don't let twats like that bother you, it's not like you haven't got a legitimate reason
for cancelling!

Thank you for the support. I asked him if he would like to make a new appointment and then he could  get longer play time, but the only date he could come he asked to be in the evening and my incall place does not allow this, also the appointment could only be at 7.45 pm he said, not earlier or later. So really specific, but it's not an option for me so that's 

Yet another entitled arsehole, block and move on, you don't need his money bad enough to put up with that shit. Take time to heal and get well soon

Hope you recover soon. I had mine removed under a general and I was in AGONY.

Block the selfish fucker.
