Appointment times are standardized, despite patients not being standard. I know I'm going to take extra time. I have multiple chronic conditions, getting treatment is a mess. But I can't arbitrarily ask for more time during booking; it's all automated now. Worse, I need to confirm the doctor kept in mind _all_ of this in my treatment plan, because I've had awful reactions when they haven't.
This is terrible for the doctor. I'm making them go over time, be late to the rest of their appointments for the day, and asking them for extra energy and brain cycles for treatment, for no extra money.
And that's not even including accommodations I might need.
I don't blame doctors for not wanting me in their practice. Controls put in place by administrators and insurance companies make me a pain in the ass to treat instead of a fun puzzle. Incentives make me more expensive, with lower payoff and higher risk.
Which... is fucked.
