Dunno bout your PCP's office, but I know some hospital workers and it seems like there's a lotta time waiting for transport because they're understaffed, underpaid. Also, lotta piss and shit related delays. Sometimes those compound.

Believe it or not, lotsa "customers" in hospitals aren't, like, operating at peak efficiency. So there's a lotta small delays that occur for normal consequences of that. A fifteen minute delay here because a patient can't move very quickly. A ten minute delay as a patient thinks they have to pee but no one can find a bed pan and they can't use a toilet. Then they don't have to pee. A thirty minute delay because they can't find the right kind of stretcher for a particular patient. An hour delay because, while you were scheduled to get your outpatient test done at 4 P.M. sharp, someone else from the Emergency Room needed that sort of test done ASAP.
