If your nurse documented you left against medical advice and refused to sign a release, its on you. You could get arrested if you got into an accident and they found out you left AMA from the facility. Of course, you would then probably blame the facility for not holding you, (as you were under the influence of anesthetic agents) and therefore you were unable to make correct decisions. Its stuff like this, and public hostility, that has now evolved into a staffing crisis in medical facilities.
The responsible thing to do was call a taxi or Uber home instead of endangering the public.
Do you think medical personnel want to deal with all of this ? If there was no baby involved, and Candace wanted to leave the hospital, I would be Johnny on the spot having her sign a AMA release and waving goodbye to her.
That's part of a general trend of treating adults and citizens as infants in need of the constant tutelary despotism of experts and the state.
I'm an adult. If do something foolish, the onus and liability should be on me, not the hospital or the barkeep. And at my age, I'm probably a more competent judge of any impairment than anyone else.
