It's amazing how much of my family's medical care I try to arrange around not Mondays (which are nuts), not Fridays (because I'm always afraid to have problems going into a weekend), not before holidays (when I might have problems on holidays when staffing is low). And if you're waiting for a call back? Once it goes past Friday at noon, you're going to be waiting until next Tuesday at the earliest.
Most expensive system in the world. Wish all that money showed up in the standard of care.
