how come I don’t see anyone but the nurse for two hours?
Because the doctor showed up late.
They overbooked / double booked (maybe with a last minute urgent caller or maybe just because they know they will have so many no shows.)
Maybe the medical assistants called out and the processing time for people is backed up.
Maybe they decided to flirt with a patient or two or took an extra long bathroom break.
Maybe they had a family emergency and had to step out or take a call.
Maybe a patient called in with a critical need and they had to prioritize that because it's a life and death situation or something.
Maybe they farted and it wasn't just a fart.
Maybe they don't like you.
Maybe their car was towed because their medical bills are piling up with insane interest and they weren't able to work as much as they needed to make the bills the last few months and they needed to take a bicycle
